I reply to all of these "new/returning player, what server?" posts with Bahamut, look for Yzerman (ign) or Lightchaos. Part of the TaylorGang linkshell, very friendly and helpful, and actually doing Abys and some other high level events.
Also look for Kalypzo, Dougiefresh, Mekdreth(sp?). I'm on during most days and nights (Yzerman) so you should find me easily.
Welcome back. Much easier to level these days, but you still need friends/connections to do some of the other stuff you'll eventually have to do.
