While in the forest area of Nexus you receive a buff call regeneration aura (4% hp 2% mana every 2 secs)
This buff is suppose to be removed while fighting Omorok the Tree Mender once you enter his area.
The exploit: Simply pull him back off his platform down the ramp and everyone will keep the buff. Heals are able to spam heals the whole fight and dps has no mana problems.
Definitley not working as intended because this makes the easy fight extremely easy.
Have fun rapEing Omorok
