Hmm.. I think it\'s nice as it is. You probably just didnt ran away enough cause I never saw that monster move an inch and it\'s not that possible that it can attack in distance. It should go after you, but it doesn\'t. The way it picks, I don\'t know, but it just attacks one, probably the first to hit him or the closest one.
About being a walking corpse, that\'s normal as well. Just exit your client and relog, it should be alright.
