When traited with Burst Mastery while in berserk mode, the warrior’s burst skill damage seems to be unaffected. In the other hand, if you swap to the Heightened Focus Grandmaster trait, it increases your burst skill damage while in berserk mode. Is this a bug, where the 7% damage from Berserk Mastery is in a different trait? Maybe there’s a damage boost that shouldn’t be there when Heightened Focus is traited. I linked a short video to show this. Can watch it in 1080p.
