he did not asked for an exploit guys

only wanted a place to lvl up to 60, so it´s not hard to be polite and help him a little.
Go to Tanaris to lvl up a little (do Zul Farrak too), then you can jump to un´goro crater and later yo Aszhara to farm blood elves (nerfed nowadays i guess).
A nice ride to the plaguelands and when u hit 55 begin to do Scholo like hell, followed by Dire Maul (loot land), Stratholme and keep going.
