The real problem isnt the SV/AV debuff its about the 1 second rend enchantments now when i aggro i hit a nm and it strips my running skill leaving me 10 seconds of slow running = grasping + axxte ownage. I really hope they dont decide to keep the rend enchantments permanent.
just agro the Nightmares before calling out the Graspings. Activate Storm Djinn's and then run around the inner perimeter of the bowl you start in. this should bring out any Nightmares. Run away to break agro (recast Storm Djinn's if stripped) and then Earthquake them. Once they're all dead then activate the quest that brings the Graspings out.
Hehe, its funny seeing people try to say Rend Enchantments buff was to make it more viable for PvP. Anyone with more IQ than a lettuce can see it was to nerf UW farming.
