I dont know who kassi is, but I usually queue up with a merc healer that recently hit 50, geared in centurion and some champ gear.
edit: ah, its a random on my team in the screenshot. Yes, im sure a random healer was completely responsible for my dps, high hit, 16 medals, self healing, and protection points. I have 100 other screens of 13+ medal games without kassi if you want to be bored for a few hours looking through them.
