I’m not a one trick, but I play mostly supports.
I usually try to play my best, wether it’s in QP or in Arcade (I don’t play comp).
I usually try to choose a hero that fits better with the hero selection my team mates make.
If I feel that I need to switch to another hero during the match I usually do it, be it to counter the other team or to synergyze better with my teammates if they also change their picks.
From a supports perspective 2-2-2 would be welcome because it will help give the game some structure. I’s really awful to play single support for 4 or 5 dps players.
I don’t really mind 3-3 comps because I rarely encounter them, nevertheless; 3-3 being meta will force the devs to nerf the heroes I love playing, as it has been happening for a while now (Brig, Lucio, Zen, etc).
It’s evident devs can’t balance around 3-3, so if they force 2-2-2 they will finally be able to bring balance to the game.
in 3 support comps Brig, Lucio, Moira and Zen (and probably Baptiste) will feel OP, so they will be nerfed accordingly. The problem with that is that they will suck as single supports or as part of a 2 support combo (Jeff said it about Brig in a recent interview).
I want to play a balanced game in which tanks, dps and supports feel balanced. If theres not an enforced structure, that will never happen.
Those are my personal reasons for wanting enforced 2-2-2.
If it doesn’t come straight to QP and/or Comp, at least I’d like it as an arcade mode.
