Our guild is small. We only have about 35 players in the lineup, 3-5 of each class. Everybody gets to play a lot, see the content and get many epics.
Progression mode can be seven days per week with early starts and extra hours. Farm status is usually only one day of facerolling through all instances as quickly as possible and the rest of the week free for alts, pvp and real life.
The recruit needs to be
Independent. We want mature players, who are in control of their time and lives and who can choose to be available when needed.
Educated. We want players, who don't need to be guided or taught how to play. All players must be capable of using forums, spreadsheets and figuring things out on their own.
Properly geared. We're not assuming that everybody has farmed every boss for months; the recruit may have crappy items. But these crappy items must be properly enchanted, gemmed and chosen.
