Collection quests must be a pain on a 5-box team. They're not so bad on a 2-box team that I run, I guess I like them actually because the extra kills required offset the reduced xp I'm getting from kills since my toons are not RAF'ed (I already owned both accounts and wanted a dual BE team without having to open a 3rd account AND upgrade it to TBC to get a BE).

I had particular fun doing the 'collect 30 human skulls' quest in Hillsbrad. Prot pally and holy priest, I pulled about 12 mobs at once and just AE tanked them while the priest healed me. I got all 60 skulls in 4-5 pulls like that
