Eq2 is somewhat like WOW as far as leveling goes. You have various levels of solo mobs, then you have Heroics which are somewhat like the Elites from WOW (maybe a little tougher then the elites).
I found there are more quests and things to do in eq2 then WoW though. I played wow as a paladin to about lvl 22ish and got rather bored.
