Crygil has announced three new in-games fixes this morning, and here they are straight from the post on the official forums:

• If a pet dies from Overwhelming Power on Steelbreaker in Ulduar, Steelbreaker will gain an Electrical Charge.
• The Doomguard’s ability Cripple now reduces ranged and melee attack speed by 20% instead of 45%. Cripple's slowing effect does not stack with other slowing effects such as Thunderclap and Infected Wounds.
• Thorim's Unbalancing Strike ability will now be used at more consistent intervals.
