Hey give other players some credits man, I try myself with weak attack... and kill it off just like that. So it's not like they don't want to share, more like they can't share since boss are too weak. Pharse 2 boss should solve the problem though since they were usually on steroid or something.
@Eab so the glitch include raid boss? I usually skip all so I'm not really sure. But it does make sense why boss seems to die so easily.
