They nerfed every tank around Rein, stop acting like this didnāt happen.
Reinhardt didnāt suddenly get super buffed; the other tanks were nerfed around him. Obviously, the answer is to walk back some of those nerfs.
Why is it always nerfs with the overwatch community, by the way? Why canāt we, at least, TRY buffing other tanks?
Or everyone can shoot Rein.
Or stun him.
Or donāt play in a bunched up group.
Or you can hide behind something when you know he has ES.
Or you can have one person with a defensive ult play out of his range and use that ult when he ults.
Iām just saying, these are all the counters to Earthshatter. We shouldnāt pretend they donāt exist just because we donāt like the skill.
Reinhardt is undoubtedly better than his competition of Sigma and Orisa. The question is then wether he is too strong or they are too weak.
Thatās only because Echo is out and Mcree/Widow were both banned, so MercyEcho was meta. Also, it was Ana + Mercy every game. Mercy didnāt replace Ana, she was just played WITH Ana all week.
We know banning Rein doesnāt make Mercy good because they legit banned Rein AND Moira and Ana a few weeks back and Mercy was still the least picked support in GM, with Bap and Brig and Lucio and Zen at the top.
Zen was seeing play because Rein gone means Orisa being meta means double shield which is Bap + Zen for supports. If Orisa is buffed at all Zen will see loads more play. Same with buffing Mercy.
What needs to happen:
Nerf shatter
Buff Orisa shield
Buff Sigma shield by removing itās delay/CD, nerf his damage range
Buff Winstonās damage versus armor
Buff Mercy
Revert Zenās discord nerfs
Give Bap 55 HPS
Bam, super healthy meta with tons of viable options for comps.
I too thought Rein was the problem until I discovered I donāt have amnesia and remember three years ago Winston was meta and Rein was absolutely unplayable.
And 7 months ago Orisa was meta and Rein was unnecessary because Sigma was too friggin good with Team synergy comp and a kit that covered a lot of bases.
So maybe just maybe 4 friggin years of imbalance saying one hero is the problem is not the problem.
The way the devs nerfed heroes and changed how OW plays is the problem.
The tanks were never balanced for 222. Thatās not Rein any other heroes fault.
If Rein was the problem he would be meta for four years straight. Try to remember how this game has played over the years as well as the fact the balance has been consistently ridiculous.
They could just fix Tank balance, instead of making the game a sniper-fest.
Ashe and echo are the most played DPS, of course mercy is going to get playtime, the thing is even in a perfect environement for mercy she still sees less play than ana in a week without rein
Rein doesnt need nerfs the other tanks need buffs.
There is no way Tein can be nerfed that wont effectively make him useless.
Decreasing barrier health is a bad idea especially now that echo is here. His barrier gets melted pretty fast before her arrival.
Nerfing his movement speed is also a bad idea as before he was pretty much useless unless he had a Lucio on his team.
Another steadfast nerf again makes him useless as before he just got ping pong balled all over the place.
An ult charge nerf may be the way to go but then itās not that great unless the team is there to mop up kills.
It would be much more effective to buff the other tanks in some way.
A sigma movement speed buff for example or an Orisa barrier cooldown reduction. Or hell even a Winston damage increase or range increase.
Or all the other tanks need to be buffed to reinās level 
Jeff already mentioned they were doing some CC nerfs for the next experimental card. I wouldnāt be surprised to see Earthshatter get touched up a bit.
About the more dps diversityā¦ is not for reinhart ban.
Mccree and briggite were banned. Then flankers can play with no getting hard countered by those two heros.
Also mccree was the dps with the higher pickrate on all ranks. Then with no mccree, you can see others dps getting more pickrate.
But you know, he is back with no any change.
Rein doesnāt need nerfs, his competition in Orisa and Sigma got hit hard by the nerf bat twice in, including their compensation buffs for the shield nerfs. Nerfing more tanks is just gonna make tanks less fun.
In the past 3 months Mcree is the highest pick-rate DPS, so when heās banned everyone who likes to play Mcree probably took a crack at other DPS and such which is why weāre seeing more diversity. Also with One-shot-maker gone you donāt need to stack up tons of shield to not get insta-picked the moment you move out of cover, which is probably why weāre seeing more tank diversity and not just straight up double barrier. Also short range DPS get a turn to play
With Brig banned, dive is a thing thatās allowed to be played again, also with a lack of Brig and Mcree flankers and WB are on the loose with little to consistently stop/hinder em. And Mercy most likely seeing more play due to pocketing Echo on her first week out, and to buff up Ashe so we have another OH-KO hit-scan and Phara because their is less hit-scans to contest her.
No matter how much you want to believe, or make it so, this whole game isnāt decided around whether rein is banned or not, and there are many other factors effecting hero pickrate at play with this set of bans
I wouldnāt count on that. Shatter is an ult and crucial part of his kit. Much more likely to be stuff like flashbang, Mei freeze, and Doomfist.
But on topic, Its Less Rein, and more that the stats on the other main Tanks maybe barring Winston and Ball are too weak.
Orisaās shield is a complete joke now with its cool down and hp values being out of whack.
Sigmaās shield while better, still leaves a lot to be desired. But the bigger concern is his fragility. He canāt dissuade any Tank from just walking into his face and brawling him to death. Sigma can put some damage out on dps and supports, but his actual dps factoring in rate of fire is awful for fighting tanks. Heās near Winston levels of pathetic in this regard, and actually worse if you take cleave into consideration and unlike Winston, has to be peeled for like heās a main support, rather than a Tank.
Rein stomps because the other Tanks canāt hold their ground or because their shield uptime is so pathetic that you donāt have enough time to slow down his advance with damage.
Reinhardt is a symptom, not the cause.
Zarya is the problem, she is insufferable to play against at any level. Rein can at least be played around and outsmarted.
How many hours do you have on tanks?
Iād have Rein meta over any other meta in any given week. First, make the tanks fun to play not shieldbot.
Then we can talk about nerfing Rein.
At least you provided something that makes sense.
Itās tiring to see these posts claiming X hero is op. Without actually knowing the issue.
Rein was so good against double shields I guess.
Oddly enough, Mei is getting further nerfs later.
As Rein is powerful in my opinion, donāt you think statistics from one week arenāt really a good measurement? Remember that GOATS was possible way long before it was discovered, you would have to see how META is formed without Rein for a long time to determine if he is at fault.
Completely agree with all these suggestions honestly. Would love to see these implemented. Didnāt think I could agree so much with someoneās suggestions lol.
But isnāt moira brig bap zen the least picked healers? (over this month)
well moira and bap because theyāre main healers
I get for this week mercy echo were and thing and the other heroes were banned, but what about this month? also doesnāt mercy work well with mcree or widow?
Regardless, I love your suggestions
Or, maybe, just maybe, rebuff the other main tanks instead of making all of them trash 
Rein keeps other tanks down when heās meta though. Itās because of shatter.
Nerf shatter, give a small boost to the other tanks.
If rein becomes trash, give him a boost in other parts of his kit.
