Same for DAoC.. that game is only alive because of the pvp, and if you are not lvl50 then it's pointless even setting foot into the pvp areas. (Except in the battlegrounds, but they purely suck.)
So because of this, it happens a hella lot. It's actually half normal for guilds to power level each members classes... the more 'pro' guilds also share all accounts, so that no matter who is online, they will always have an optimised group. the French guilds also powerlevel their crafters so they can all get the uber items for free. Necromancer ftw when it comes to powerlevelling. Ultimate pve toon
