Blackwing Lair -- Hotfixes
A few hotfixes just went live in Blackwing Lair:
--Vaelastrasz's Burning Adrenaline spell will be cast less frequently on his primary aggro target. Random targets will still gain the BA spell at the same frequency as before.
--Fixed a bug that was causing Blackwing Warlocks to cast too many portals too frequently. As a result of the fix, there should be fewer Fel Guards to deal with.
--Reduced the duration of Firemaw's Flame Buffet from 60 seconds to 20 seconds.
