With Mystery heroes having no control over what you play, the game mode should restrict how many of each Hero is allowed on each team to 1 like the regular game modes.
Going up against 2 or 3 of the same Hero can be very frustrating and not fun. The game wasn’t designed for a team to have multiple of the same Hero so why does Mystery heroes have this feature?
I have not made 100 posts about this subject over the years 
because this gamemode literally is called mystery heroes my friend.
No actually the game originally was designed for this. 
I think “designed for” and “oversights” are different things
Like I could say the game was designed to not have RQ…or the game was designed to not have a set amount of tanks…or the game was designed to not have a comp mode
All things that were changed later…clearly the devs can look at things and say “that should/shouldn’t be there”
MH was designed to not pick your hero…it was not designed to have no limits just like the rest of the game wasn’t either….and any time spent looking at what happens in MH when hero dupes show up would tell you that it’s even worse for that game mode than it ever was for the base game mode
Its the most objectively broken thing in all of OW
The game mode came out the same patch no limits was removed from the game…clearly an oversight, which coupled with blizz’s general neglect of all game modes not named comp/qp, leads us here
The only change they have ever made is limiting roles to 3 (but it was designed to not have role limits!)…nice but nowhere near enough
Because it’s random.
It’s not Mystery Heroes fault nor other arcade modes fault that the devs to make raid boss tanks, passives, and a 5v5 format that was never meant for arcade modes.
Don’t change the mode into something further from its ow 1 greatness.
Get 5v5 balance changes out of arcade modes
5v5 has nothing to do with the topic…
Yes it does. Just math in general.
You reduce six to five that ups your probability of getting duplicate heroes which is what op is complaining about.
I noticed this too! I play a decent amount of mystery heroes and ever since the start of the new season team comp slowly devolves into double and triples of single characters. it wasn’t doing that before! you’d occasionally get a duplicate sure but not at all like the rate that is happening now. I wonder what broke the RNG.
No it doesn’t…cause the same request was made OFTEN during OW1…and my memory might be bad…but I’m pretty sure 5v5 didn’t exist then
No just your understanding standing of mathematics and how probability works.
Five is less than six l.
Which is more likely to give you less variety?
A composition of 5 or a composition of 6?
It’s irrelevant…its bad in both cases
If it’s more frequent now all the more reason (though as someone who plays that game mode 90% of the time it’s not noticeably more frequent…same awful though)
It would lose a lot of the point of the mode if they added more restrictions on heroes. I love MH as is.
It’s not irrelevant if you do the permutation calculations. It increases the probability of both sides in a match encountering duplicate fights more often.
Which then avalanches into 5v5 already being a more stomp heavy mode.
Both issues stem from 5v5.
It’s the same reason Vegas has different odds rewards for 5 card poker over 7 card poker.
It’s irrelevant because it doesn’t matter if it’s worse or not…it was also bad before…ANY amount of it is bad (I’m not arguing your math)
Not sure why we’re trying to make everything about 5v5
Pick any combination of numbers…it’s bad
im on the opposite end, they should allow hero/role stack up to 5 in that mode instead of locking it to 3
As a tv show once said, “numbers never lie”
I’ll help you with a more relevant visual aid to understand why it has always been a numbers issue as well a 5v5 issue.
Remember when Soldier did 20 dmg per bullet and just a 1 difference between previous 19 DMG per bullet.
Now just take how that single number choice had an impact on One hero across the game.
Image you have 6 heroes in a game of chance. Now you subtract one from the composition.
Are you going to say that doesn’t have an effect on the odds of increased probability of seeing multiple heroes?
It’s a yes or no answer. Not a how you feel answer.
Because I feel 5v5 MH is way worse than 6v6 MH and more stompy especially with role passives making it further stomp heavy.
But that’s just my opinion. The math however, says you’re more likely to get two and three of a kind on heroes in team comp since their is less to divide by to spread out the probability.
If you can’t understand that then just see videos on poker or dice rolls.
Not saying what you feel is invalid.
I’m saying it’s simple math issue. Just as why tank doesn’t feel right.
Well let’s look at the numbers. DPS has 2. Support has 2. Tank has how many …? It’s almost like thats a number problem 2, er to, I mean too.
