hey there mmowned, ive always wanted to try to post something useful on here but never found anything until now i hope...
The spot- Dragonblight at the onslaught base camp
The mobs here at these camps are extremely easy for aoeing grinding they range from lvls 70-73 you can easily do this on a greenmachine mage at 70. they give about 950xp at 70-73 and about 800-850xp from 73-76. Alls you do is round up one camp at a time and just aoe them down the key to is not to let them touch i do this on a frost mage and have been doing it since lvl 70, just cast mana shield and ice barrier then mount gather them up and frost nova stand back and blizzard them down usually takes about 2 blizzards you'll get one blizzard off before they unfreeze you can either just cast another blizzard (it will get about half way done before they interrupt) then just do a quick aoe arcane explosion ect or another blizzard. There are about 5 camps scattered right by each other and the respawn is very quick not instant but quick enough to just make a nice little route running from camp to camp. Ive found 2 boe blues here and tons of greens, frostweave cloth ect there are herbs at the surrounding trees.
I will upload a picture if requested the spot is rather easy to find its right above naxx
P.S. Sorry for the wall of txt and piss sorry to all the grammar nerds its the internet damnit not english class.
