The official notes for Patch 3.3.3 have been updated by making some changes to the glyphs official, and introducing a small change to the encounter of the Blood Queen Lana'thel that will slightly affect the mechanics.
There is no really big change and hopefully we will have it on our teams soon.
Icecrown Citadel
- Wrynn's Force y Hellscream's Warsong now also increase the effects of damage absorbing spells and the health and harm of pets.
- Blood Queen Lana'Thel: Pact of the Darkfallen now applies damage twice as fast but doing half damage. This change will make removing the spell a bit more sensitive.
Death Knight
- Glyph of Icebound Fortitude now always grants at least 40% damage reduction.
Rogue
- Glyph of Feint now reduces Feint's energy cost by 20 points (was 10 points)
- Glyph of Expose Armor now increases the duration of Expose Armor by 12 seconds (was 10 seconds)
- Glyph of Deadly Throw now increases the slow effect of Deadly Throw by 20% (was 10%)
Priest
- Glyph of Imprisonment Scourge now reduces the cast time of Shackle Undead by 1 second (was 0,5 seconds)
- Tier 10 4-Piece Healing Bonus: Redesigned. This bonus now increases the effectiveness of Word of Power: Shield by 5% and Circle of Healing by 10%.
