We all know, warsong and ed is dying most likely due to bad development since charge have change.
People who leave these server specialy warsong lookin for simillar server with new start. Some where they can kill kel'thuzad
DDD am serious.
Atm only good counter project is mentioned rebrith wow. So the community from let's say ED will go to unknown project called kronos or good second project called rebirth? Someone said ppl reroll on rebirth and i don't think they will leave they newly leveled char just for another project who had 2 "bad starts". Scripts aren't good argument, since common guy care about kill and gear. He don't even know how should stuff work. However population is something that he understand very well
There's only 1 option for kronos which is pull community with taste like warsong is, which means higher exp. rates
And about vanilla feelings. True vanilla feelings were while leveling first character in wow. Sadly it can't be reproduced.
