cross classing berserk wouldnt work because that would also give access to berserk for monk, due to how the cross classing works, which you know will cause even more hate.

aside from that, as far as utility goes drg should get a 10% int down debuff applied to disembowel, make it a 2 part debuff so that it could be overwritten by the int debuff from dragon kick and vise versa, the 10% int debuff make a surprisingly large difference when you do/dont have a monk, this would help bridge the gap.
