I'm mostly doing pvp and when I do pve it's the generally daily pledges to get geode's, keys and monster sets. In pve I got 2 tanks, 1 Dragonknight and 1 Necromancer. I don't do trials so I'm not able to say anything about the dps situation there.
After Reading the post about nerfs to damage I was prepared for lengthy runs doing dailiy pledges. I can't say if there is a difference before and after patch, some runs go just as swift as Before and others takes a bit longer but my experience is that it's more up to grp composition and is only marginally affected by nerfs.
Don't get me wrong, I fully understand that no one want's their damage nerfed but isn't it more of a case that it feels so random and unpredictable ?
