Hero bans have already been debunked by Jeff, but I personally thought it would have been a decent idea if it came our right.
2-2-2 is loved by the playerbase according to polls but according to the forums full of plat hanzo mains, it is was and is a disaster. In my opinion, I do not like 2-2-2 because of it’s many drawbacks like increased queue times for all roles except for the tank waiting room which has transformed into the Sahara desert. Although role queue has its drawbacks, it makes the game feel better because you are guaranteed 2 tanks, 2 supports and 2 healers. Some say it limits creativity, but if creativity leads to another year of some Pandora’s box comp, I’d rather take role queue. I’d rather play tank with supports rather than a mix and match of roles because I know what I’m getting into and I don’t need to pray to rnjesus.
