I'm quite pleased to see a bit of a grind to it, but again, I'm an ex EQ player and found WoW far too simple to progress through the levels. It lost the satisfaction of gaining a level like dinging through the hell levels in Everquest used to.
Im lvl 30 atm and have done a bit of grinding but you can 100% level without doing any grinding at all if you level all gathering skills as you go , do all quests for your level or closest , backtrack a lot , level crafting proffesion/s and do the city quest chains
there isnt a huge amount of quests but its just enough to level without doing any grinding if you do it right
