I feellike its a good change, but can lead to just as much QQ. Got tanks owning your team and a horrible Reaper that locked the character? Better hope you can position Bastion well. Maybe a Pharah? Yeah, sure, if their S76 standing behind the tanks is terrible. Very tiny, non in depth way of stating, that countering will be that much harder now. The only real alternative is to play with friends or pray you get people that will trade roles/heroes with you.
