Lol, I think my druid started on PoP around 65, at 72 I'm working on my elemental drops. (and missed the last two weeks successful runs...grr, but grats on Xegony DOOM!!
)
It has been hard with open raids as Ros mentioned. Man, I could stand to never have to do MB again...ever!. Backflagging constantly. I've probably done all the pre-elemental raids, successfully, 3 to 5 times each, some more.
PoP raids are notoriously complex in that they almost always require some off-tanking/and or other massive mob control, so you certainly don't need the numbers that you used to need but still need a good solid raid with ample healers, a few good tanks and massive dps. We're running elementals with four or five groups with average raid level usually 71 or 72....and they're not a cake walk.
An aside: The open Doom Pop raids started shortly after the inception of Peoples of Doom, Gnome had never intended to keep running open raids, once we had a force large enough in the guild. They just never became sustainable within the guild, though we get a great turn out.
