IIRC it has before and been okay'd, because the weapon being used to deliver that damage is as far as basically anything else in the game works also means the weapon is being used to deal that damage. I think that was the reasoning anyways.
Agreed, Brutal Necromancer is brutally broken, but even base Necros is iffy at best on balance, certainly above the rest of the LSP spheres classes. But as you say, everyone will make the comparison (despite being a totally different non-DDS publisher).
