No matter how much you want to defend your 2/2/2, the moment 1 role gets 12min+ queues you know its a garbage system.
Make it ATLEAST 1/2/1 with 2 slots that can switch to whatever they want. Not only fixes it the queue, but it also gives some more variety to those stale 2 2 2 tryhard metas.
Had too many games where my 2 dps hitscans cant kill their phara, mercy once and im like “yea if i could just swap from my healer to a dps and fix this issue this game wouldnt been a stale stomp and waste all our time”.
Limiting everything to 2/2/2 also not only shows the incompetence to balance properly but also takes out about 80% of the fun and makes it some tryhard esports. Ever played Dota2? If they attempted to limit picks to their positions the game would be kinda dead as their are 1000x more ways to play and make strategies with all hero combos available.
Heck if you even allowed 2(1) / 2(3) / 2 you would fix the queue times instantly and not even break the game.
