I don’t even remember anyone asking for 5 v 5.
It feels like they’re doing it out of sheer laziness. 6 v 6 is harder to balance and therefore more expensive. if there is a choice between ruining the customer experience or blizz employees actually doing their job, they’ll side with ruining the customers experience 10/10 times.
Blizz is just not capable of solving basic problems. Enjoy the husk of a game until it completely falls apart under the weight of many multi-year unresolved issues.
5v5 has experienced the exact same thing. Almost every major complaint cycle OW2 has had was a direct result of 5v5 from weak supports, to flankers, to snipers, and all the way back to OP supports. Even some of the problematic heroes you listed like “Roadhog” were made way more problematic through the change to 5v5.
As more time goes on, my belief in this fact gets stronger. I didn’t like the idea of 5v5 at first, but I gave it a chance. The novelty was cute for a week. Then all my friends that came back stopped playing because it’s genuinely so much worse than what we had before - simply an excuse to market OW2 as a new game when in reality it was just a downgrade in most ways. Only real upgrade was the ping system and even that can be annoying when it won’t ping the thing your crosshair is on, instead opting to ping something in the corner of your screen.
My overall point was that people tried putting up with most of that stuff because of double tank being the solution. It’s not that DPS/Supports had solutions to these issues really in any great fashion. OW1 had many annoying mechanics and that the solution most people came up with was put the tank on it.
5v5 with the loss in tank made these mechanics more exacerbated and I’d argue lead to dealing with it faster.
I’d much just prefer they took the WoW route and released Overwatch Classic as it was from whatever is considered the most popular patch version prior to OW2 releasing.
With the direction of the current game I’m not really interested in 6v6 OW2 and would prefer the option to play an untarnished version of the OG game 
(just my thoughts).
Double shield was always a thing, every tank player was boosted to oblivion by it. Dps queues were 10 minutes because of waiting for two tanks to throw your games. Nobody wanted to play tank in 6v6.
Rein, Sigma has tons of synergy on attack. Way too much shield uptime
5v5 is easy to balance, but they keep overbuffing tanks like Hog, Mauga recently.
my argument to this is it’s easier to balance something with more legs (like a table) and thise things can also hold more weight because of the division of labor
And nobody wants to tank in 5v5 either
Not the boosted Dps calling other boosted 
Clearly not
Only reasonable thing you’ve said
See Zarya & Rein be in every match?. No thanks.
5v5 will always be the most flawed decision they ever made.
Having to fully rework entire characters to force this thing to work is proof enough that it isn’t good, it isn’t easier to balance and is killing the game. Slowly over time homogenizing what made OW so fun and removing all strategy and thought in the process.
That only happened in low ranks, ohhh waiit…
What if remove the tank role completely and extend the tank abilities to the dps and sup roles?
I mean no matter what anyone thinks about balance, if we were in 6v6, things would be exponentially worse, thats for sure.
I dont think Hog is an issue, but Mauga’s range, power and skill required to pull off the “bullying” are indeed an issue. Nothing to do with 5v5 tho, imagine that dude in 6v6 
It depends really.
6v6 was best for tanks. There’s a reason why people used to call it ‘tank-watch’. The only tank hero that feels good to play whose playstyle didn’t exist in OW1 is doomfist. But who’s to say that tankfist won’t work in 6v6 with the right tweaks?
5v5 is best for a lot of DPS, but some didn’t transition well like junkrat, reaper, and cassidy. But most other DPS are doing much better in OW2 overall thanks to lack of second tank. DPS only feels weaker because of support power creep as well as DPS damage nerfs, both of which were necessary since 5v5 benefits DPS the most. Although they do need to tone down on support sustain however.
For supports, it doesn’t really matter, the role seems to function well both in OW1 and OW2.
Here is my experience in 5v5 open q. Whenever team goes 1-2-2 it is really hard to get a kill because that single tank is sustained by supports like no tomorrow, so i decide to go after supports but just as i land first shots, i am eliminated by the enemy sniper and since it’s open q the only way to counter it is by 2 tanks, 1 dps and 2 supports. When Samito sparked a even bigger debate about 6v6 vs 5v5, Youroverwatch was quick to say that 5v5 was for hard-core fps players whilst ignoring the casual playerbase. Let’s not forget that OW1 did not get proper competitive publicity when it first launch. In conclusion 5v5 is not casual format and we need 6v6 back but not just because of casual play but also because of rock-paper-scissors meta.
I think a main point that the 6v6 crowd is ignoring is that “double shield”, was not the main reason for the switch and rather to streamline the game, remove oppressive tank synergies that dictated the game and limited tank creation, reduce the queue times and make DPS feel more impactful.
Not to mention that we now reworked a lot of tank/buffed them, added tanks who are not made for 6v6 at all, changed all supports and multiple DPS.
We right now have balanced more in the direction of 122 than we ever did for 222. That alone is a reason why we are not going back (not to mention the other problems).
Maybe we will have OW classic some day or a 6v6 mode, but even just looking at all the new maps/modes, they are not designed for 6v6. Its also not like anyone loved to play tank back then. Tank was the reason why queue times were so extremely high… to the bitter end.
All of this time and energy was put into 6v6. From 2015 through to 2022. Even if the years of patches during the OW2 content drought don’t count (balance patches were more frequent in 2020-2021 than the preceding years, btw), then we can still count 2015-2019.
How many more years of time and effort do you think it would’ve taken before 6v6 finally worked?
“We should go back to 6v6. Surely this time they’ll be able to balance it” is such massive cope.
At the moment, 5v5 mainly has all the same issues that 6v6 had and a couple of unique issues of its own. The upside is that all the issues inherited from 6v6 are way more obvious than they used to be and we actually have a roadmap for them to be fixed. People actually understand how the game works now. That’s a good thing - even if one of the side-effects of that is that people counterswap in Quick Play more often.
I would easily take that over people in the Pro community spending months pretending that somehow D.Va is actually the real cause of GOATS (a discussion that actually happened back in the day).
I think role queue was implemented in August of 2019. So the devs probably started taking 2-2-2 seriously between 2019 - 2021 which is only 2 years. But you’re right that tank synergy had a lot of downsides to it not just upsides. So 6v6 vs 5v5 is matter of personal preference, since both have their own pros and cons.
Those reworks have nothing to do with format and although they fixed the cc problem, they kinda ruined some characters identity and also I feel like McCree, Mei and Brig are as easy to use as they were before they are just more complicated with the “Soft ccs” so the reworks did not help in those aspects at least I don’t feel like it, but, it did help with lowering cc.
Yeah and it was fun, but, then goats came in something fixable with role q, and then tanks had to play orisa sig because of the cc and double shield was a thing and that was fixable only the last years of 6v6 were bad and they gave up on the game in 2020 so no updates to fix it (they were probably saving them to ow2, but, with PvE cancelled they had to change the game to 5v5 to call it ow2), but, 5v5 was bad from the beginning it took 3 or 4 years for 6v6 to start getting big problems and it took some weeks to 5v5 so I guess it’s obvious what the superior format is, but, hey the key to make everyone happy is having both modes.
