psh... we're doing fine on Indigo imho. We may not have the endgame raiders to clear anything past RT, but hey, them's the breaks for rolling a PvP server. My guild is fantastically full, and more join us every day... mostly new players but they're eager to learn and progress.
If you're having trouble with the number of endgamers... well gee, perhaps you should help make some more? Recruit a newb and train him/her up, when they get all growed up, they can help you back!

Then do it again, and again and again till you have an army of people who've been trained to play like you and yall will have a synchronicity unparalleled by those guilds who simply recruit the "good" players from other guilds and don't take the time to work on team cohesion.
Warning! This may require some of those Endgame
(*ahem*) players out there who are hording all the gear and demanding outrageous prices that can only be paid for by gold-buyers to step down off their high horse and see that by creating a clot in the progression process of new players to hold a monopoly, results in the server bleeding out of anyone you would one day try to recruit.
