DKs die instantaneously on the PTR, I faced some 2k Dk/Hpal on the PTR and we killed the dk before his healer could get into the smokebomb multiple times. They do pretty good damage, but it doesn't matter.
Warriors damage didn't seem to scale as well as other classes. Still have good mobi and CC but the raw damage isn't there as much, at least from what I could see. Only faced a warrior/hpal team once or twice.
You know what I mean.
2k PTR = 1.4k retail.
Everyone who's been on the ptr knows that.
Also you're talking class balance after playing a 2s game? Lol
