A forced 2-2-2 role queue comp would really change the game up and make it a bit more interesting IMO. Also, probably not agreed with, but if there was role queue a separate SR for each role would be kinda cool. Like 4.5k dps player, but only 3.5k tank player
I think the idea behind not having 2-2-2 in Comp is if the other team has just flat out better dps. You have the option of going tank and being more viable. (Not that a single person does this ) but might be why
