Once you find guilds in the right tier for you, the next thing to consider is how active you plan to be. A big thing to look for is a guild is one that is close to full (guilds can have a maximum of 50 members) and if you want to do a lot of raids, one that has a high daily raid ticket contribution (each member can contribute 600 tickets from spending light side, dark side or cantina energy, for a guild maximum of 30,000 a day).
