Current situation on Prog servers is as follows:
SK's are a dime a dozen. Most are boxed, due to HT being stupid OP atm. 32K hp raid mobs and HT doing 5k per click makes raids boil down to who has the most SK's that are not afk.
Zerkers/BL are not in game yet.
There are alot of monks due to h2h damage scaling being better than most velious weapons currently, and we are in classic still with Kunark opening in about a month. Monks are judged by their pulling skills, as always.
Pets are also OP, with magician pets being far, far superior with focus. I've seen several mages app to my guild that are lvl50 and mostly nekkid due to not needing gear for the most part.
All this looks bleak for classic, but honestly unless you know your class I don't have much trouble as a 50 rogue with BIS gear (aside from the cursed PoSky dagger, items for that never, ever, friggin drop it seems) outdps monks. So what does that say for their hax h2h damage

.
The group game on Fippy is still well alive for early levels, but Vulak having lower population is pretty dead from what I've heard. But I don't play on Vulak, so take that with a grain of salt.
Edit: It's funny though, Pyro. Twisted Legion is the #1 raid guild on the server, and I believe alot of the members are from Realm of Insanity, or at least, the higher ups.
