Will throw mine in the mix. Right now it's only me, but I welcome anyone...especially others new to Mulitboxing looking for a good EST/East Coast server.

Guild: <Synchronicity>
Server: Auchindoun - Alliance Side
BattleGroup: Retaliation
Data Server: Boston (I live on East Coast, yes, it makes a difference in PvP).
Server Time: EST

Decent server. Lower/Mid population, feels very active. Economy seems pretty normal/stable. Probably is a bit Horde heavy but doesn't feel to unbalanced. (I'll know better once expansion comes out, I'm a transfer about 6 months ago). Typical trade chat drama (I never have it on). World PvP is not really existent, but you WILL get ganked if caught alone on dailies, etc. Overall I'm happy with it. The only downside, and maybe this speaks to balance, is that Alliance does not own WG nearly as often as Horde. I'd say 40/60.

As for the Battle Group. I think it slightly favors horde in all BGs except AV (Lyonheart would know better than I).

Note that my team (Pally/DiscPriest/Mage/Shammy/Lock) is only at 66, but I'm trying to fast track them to 80.
