Had the same setup as we normally has.
Raided Vicus (did around 5k top damage except for the epic 10k during his rallying)
Had same problem all the way through to the warehouse portal..
Buffs were bugged at times, where half the raid lost all but 10 buffs etc.
Tried with and without bard in group, did some difference with bardsong on, but nothing
near normal.
Procs where mosly higher damage than the actual attack.

Went out hitting on some green 2-dot mobs after raid. Removed all buffs and then relogged
and still hits for half of normal.
The triple strike chain does around 2-3 k damage and with the "1 extra hit per strike" I get about 2k more damage..
The Exploding hearth chain does maximum 5k on last part of the chain..
Tried respeccing (in case my stats went bugged) with the same result..
No one else that has same problem?
