@Demomo: you're not the only one who's experience this, a lot of other people has been saying the same thing about Cerb suddenly having perma -PDT. If I remember right, it's even been reported as a bug on the official forum.
Not sure what was wrong with cerb, but CDC was doing 30-50 and shield bash with 90 aegis and ring/hands was doing 80. Switched to joyeuse at 50% and it was doing the same melee damage as 85 alamce. Took almost 2 hours because of this. Never again.
