I personally will grab a bear pet and go BM. Gogo nearly 3 second CD swipe. Spec him for max damage and get the increased healing talent with the extra points. This is what I did to level 80 but i used a gorilla since they were the only ones with thunderstomp. Gonna use 2pc t5 and gather a bunch of mobs up to volley, and heal my pet with the volley. Not going to grind mobs, but it makes quests so much faster when you do the entire thing in one pull. Might possibly use glyph of volley since i did have mana issues on my way to 80 using the same strat.
