I'd suggest taking a look at the Guild Listing thread: http://www.swtor.com/community/showthread.php?t=588084
. Under the Focus part of each one the guild lists what its primary focuses are.
Esoteric Order (My Guild) takes part in all aspects of the game. From Raiding and PvP to Socializing and RP. Granted we are heavier on some things than others, but we do enjoy everything
