I'm still stuck in the days where 2/3/5 was the comp for a 10-man raid.
Although I knew so little about raiding back then...hell it wasn't until ICC that someone showed me what happens to raid DPS during hero/bl via the real-time dps graph in recount that I found out it was so valuable.
But I remember Moroes being a b---- to heal, although I think that varies widely by patch.
Oh and bad groups had serious trouble with Curator.
