Depends on who it is. If "illumanti" ksed you before. Fuck them. Ks them to death. Tormentors never ksed me. Even in bowl boss, apostillo waited for waggy to finish off a shaula. Thats class.
Bowl bosses = free for all since its jsut chaos. But if I see a tormentor taking OBL and Samma by themselves where there arent 500 oters human hitting it, id protect them from orcs.
