ZG trash farming also does not work for every class (as he already mentioned). It worked perfectly on my hunter and my warlock, but my mage just gets twoshotted from the not kitable berserkers and also aoe farming elites (like the crocos) was a tough call when not all CDs were up.
So best way for 81-90 seems to be simple questing. Finishing hyjal, collecting pandaren treasures plus one or two instances do the trick for me.
