I'm somewhat new to WoW, I leveled a warlock & hunter to 20 once & a few others to 10 a LONG time ago before stopping & now wanna give WoW another shot.

Just wanted to know a few of the the major differences between a warlock & mage in terms of playstyle/endgame/pvp/etc. (Any links would also help) Also, I plan to go with a nightelf or human regardless of class (Any suggestions on which one is better for a mage or warlock?) Only really going to be a casual player if that helps.

Thanks for your time ^^
