Sure, they have a dps party buff, but it's just 3%...
And the aoe heal is very conditional and very light (potency 100, lasts 15 sec.)
Yes, their dps is great, but it'll likely be adjusted in time. I only hope they don't nerf it into the ground like some sort of punishment for it being strong like they did to DK in WoW.
"Welp, ppl be angry, so we'll change the potencies to 100/105/115 and 120/120/130 across the board."
