have players in your guild start level-1's in a starter area where the quests are fast and packed tight ( not too much running around) have other guild members create 1's get invited to guild, do just the fast starter quests and the point having to leave, delete player, recreate another 1....repeat.. imo using hunters with BOA's make the process really fast too. do not recommend grouping it slows the process down imo
create player, then mail BOAs to it, get guild invite do the quests, mail the BOAs off the leveler, delete, repeat
HU you do all the quest till you are sent go to goldshire, delete repeat
Worgen seems to work best for me and produces higher XP #'s, do all the quests to duskhaven and 2 quests there and delete/repeat. if you are bored and decide to go past duskhaven...BEWARE, last mail box is there and you will not be able to delete a BOA geared player till you have done all the quests and are at darnussas to mail the BOA's off your player
UD side is good too imo
haven't tried goblin yet
