Return of Reckoning

ok, a bit of context, i play as a black orc wit cr 15, i am currently in greenskin chapter 5, and i was finishing the public event "danurgi's rangers" as i arrive at the third phase of the event, i find myself with a problem, a guy named stoutbeard, a bot, is the last guy i need to kill to finish the event, but, as i start attacking him with all of my buffs, i see that i only do a minimal amount of damage, almost to nothing while he did enourmous quantity of damage, now, is it me that sucks, or is it a problem with the game

Easy PQs are for soloing, normals are for groups.

I don't know the PQ exactly but I guess the PQ is not labeled as easy. So if it's a normal or hard PQ the boss in Stage 3 is most likely at least a Champion or Hero Mob which means you cannot really fight him alone and need to find mates to clear the PQ.

pq is 6-9 players,
Strongbeard is a hero so does more damage takes less
