Angry Grimace said:Shadow Priest changes are pretty much the most straight up buffs w/o nerfs I've seen Blizzard try in a long time :lol
Shadow:
Priest
* Improved Devouring Plague: This spell now deals 10/20/30% of its total periodic effect instantly, up from 5/10/15%.
* Shadowform: This talent also now causes Devouring Plague, Shadow Word: Pain, and Vampiric Touch to benefit from haste. Both the period length and the duration of these spells will be reduced by haste. In addition, the mana cost has been reduced from 32% to 13% of base mana.
* Vampiric Embrace: This ability is now provides a 30-minute buff that cannot be dispelled, instead of a target debuff.
Glyphs
* Glyph of Mind Flay now Increases the damage done by your Mind Flay spell by 10% when your target is afflicted with Shadow Word: Pain.
* Glyph of Shadow Word: Pain changed to - The periodic damage ticks of your Shadow Word: Pain spell restore 1% of your base mana.
* Glyph of Shadow now increase your spell power by 30% of your spirit for 10 sec. (Up from 10%)
It doesn't sound like a lot, but most Shadow Priests are carrying a reasonable amount of haste anyways to fit the correct amount of Mind Flays while casting MB on CD, and usually running three dots at once.
Finally, some much needed buffs.
