How long are respawn timers on rares and how generally do they work? (does timer start from spawn of mob or when mob dies)
I am trying to get my http://www.wowhead.com/achievement=2257/frostbitten and http://www.wowhead.com/achievement=1312/bloody-rare
so I would be mainly interested on how respawn timers work in those cases,
but knowing how they work on other rares like ones on 1-60 areas, MoP rares, TLPD, Aeonaxx and what else wouldn't hurt either
