Wait what. You wiped on first boss with nightmare pilgrim buff?
And you're a clicker?
I don't click on my other classes, but as a mercenary it's much to easy to click and not have to keybind, i can't get away with it on my Marauder.
As for wiping on the first boss, I recently dropped quite a bit of crit from my grear so my DPS was way up and we accidentally pushed WH just before the third pool. Not very fun haha.
