If you just started, play the game normally, you only ever get to experience that once. Ever player has fond memories of their first play through, i did mine on my Paladin in Retribution spec and i remember so many things that happened, the first time i got ganked lol, dude flew out the sky and smacked me dead. Taking time to enjoy and discover the game is amazing dude, you'll have the rest of your life to play at max level and chase endgame results but you can never go relive the first experiences you have with WoW
