The one character per game can make it or break it for some people. Its understandable, but at least the moba-esq item system during a match can somewhat counter enemy comps. Sadly if you get bad teammates you’re screwed for the whole game, in OW at least if one person was slacking with a character they can switch or their teammates can switch to compensate for their short comings.
Oh man are going to be in for a treat once Jenos (Support) comes out. But luckily he’s a soft healer so most of the time he’s best paired with another healer or one damage comps.
