leveling to 80 with everyone is going to be pretty hectic. u are fighting quest mobs with both ally and horde groups. prepare for massive pvp to get quest done. i know some ppl will try to get the first to ding 80 achievement in my server. they have a group for instance grinding as its the fastest to level and gear up.

i'd prob get a group to instance grind all the way, and once u ding 80, u can do the crappy quests for rep as well as more gold to get your mounts.. i foresee that ppl will ding 80 and start arena-ing for ezmode gladiator (especially 2v2) for the 1st season in wotlk.
