I run into some issue in Final coil as a bard in term of dps in the final coil. In turn 11, I got some report that my dps is low at around 300, which is pretty bad. My gear set is ok at around 113. I usually start the fight with Straight shot, bloodletter, blood4blood, internal release, venom, hawk eye, windbite, raging strike, barrage, blunt, and finallly flaming arrow.

My dps usually remain high in the first 2-3 minute inot the fight and then I will suddenly drop down to 6th place on the hate list and will remain at 6th place. I remember to reapply dot as much as possible and reapply buff. What am i doing wrong? There is surely something wrong when I keep hearing other bard can pull 400 dps while i am stuck at around 300.
