Just got my monk to level 85 in less then 3 hours from 80-85 (No level granting only heirlooms)
there is a spot in deepholm
If you go there you will notice trolls falling down from the upper rocks - if you go up there you will see a bunch of em in groups - 5-9, these mobs have a spawn time of around 5seconds and grant the same xp as normal mobs would.
You can mix and match w/e you want to do with this (you aoe friend heals w/e)
What i did to get from 82-84
Me + Monk healer + Shadow priest
- Me and monk stood in 1 spot and was aoeing the mobs down while the shadowpriest was gathering them up - We were aoeing about 15-20 mobs constantly for 1 hour which dinged us all 3 from 82-84.
There are people wondering how other people go from 80-85 in almost no time - so this might be it - NOtice that you don't have to be the level range of 82 to do this - you can get summoned inside Deepholm at any level (saw a 64 alliance priest wanting to try but we quickly ganked his group and put a stop to it) -
