By "unique" I think you mean "overpowered". The boss uses the standard grenade launcher (already unbalanced), but on top of that, it puts after-burn on the target? Please word that correctly, because you said his rage is "after-burn" and regular shots are "after-burn". If you mean what you are saying; that's complete idiocy to put that unbalanced boss into Skial VSH. It would be the only played boss if put in to Skial VSH, so I don't recommend this boss. We already have a big variety of bosses on Skial VSH, and personally, I think the variety is perfect already.
