I was able to get in a few matches last night as Warrior, in both 8v8 and 4v4, I had instances where my medal stack was up to 6, one time 9, and I still had no problem keeping alive properly using my CDs and clinch timing on Thrill of Battle/War. Also tried out BLK(new changes=Fun again ) and had a match where the Opposing Paladin had 9 stacks with <60 secs left and we couldn't kill him(I even got off a RS powered T3/F3/Elearrow/Fire4/tc'dT3/Scathe). I think the heavy medal would decimate a non tank, but it is at least working for good players who play tanks.
