This would be perfect because since alot of people solo them your only hope to kill them is to camp there and to camp there for TWO hours for one rare is very overkill. 30-45 min is ok imo. But whatever they do dont ever make them have the HP the zaralek rares had ever again. Oh and BTW you also stand the risk of some hunter taming it, wouldnt that be something you wait for 2 hours then see some hunter tame your rare
