Red Beam blockers should be careful when moving out of Void Zones. It is
usually possible to move forward or backward enough to not take damage
from the void zone without causing Netherspite to shift position
(thereby causing the blue and green beams to shift off their blockers
and onto Netherspite).
Netherspite will no longer cast Nether Burn while crazed. http://wowwiki.wikia.com/wiki/Patch_2.1.0

The damage dealt by Netherspite's Nether Breath has been reduced.
Sadly i dont have any leads on how much it was decreased.
