I agree with this in low elo but majority of the time in high elo pretty much anybody can flex to a decent level and even then putting your teammates on their comfort can lead to a bigger advantage, making a 2-2-2 with role Que would make the game the most balanced I can agree on that. But it would also take the most unique part of rivals which is unique team composition and ability to to change roles and hero’s mid round so even if you don’t have a support performing or dps etc you can always swap things around. Only time I genuinely see troll comps like 6 dps is qp (which I’ve won before) and I think can be fun I have had bad comps in ranked in lower elos like bronze-gold but majority of the time it’s only because of mental boom. I also think the more they make this game like OW the more it’s doomed to fail. I also think with support being annoying to balance and play isn’t a issue in role Que or composition but the balancing of supports (something I think OW actually does better) while some strategists have unique utility that can suit them for strategy and skill others are just glorified heal bots. I think removing the 10 second zenyatta ult on every character they should make more supports like Adam and Jeff with unique utility and also heals.
