It’s going to be Spirit -> Crit rating, and it’s going to be via Molten Armor.
- Molten Armor now causes 170 Fire damage when hit for all ranks (Up from 75/130/170) and also increases your critical strike rating by 25% of your spirit.
- Glyph of Molten Armor – Your Molten Armor grants an additional 15% (40% total) of your spirit as critical strike rating.
That’s… neat, I guess? Now both major mage armors use spirit; one uses spirit for mana regen, the other for additional DPS. Mage Armor and Molten Armor are mirroring a Hunter’s primary aspects more and more every day…
But whatever. That’s design philosophy rambling. Let’s talk numbers.
Depending on how much spirit you have, this will work out to either be a nerf or a huge nerf. For simplicity’s sake, all the numbers from here on out are assuming the mage is using Glyph of Molten Armor, and is therefore gaining 40% of spirit as crit rating.
A mage needs 45.9 crit rating to gain an additional 1% critical strike chance. The 5% crit mages currently gain from Molten Armor is equivalent to 229.5 critical strike rating.
Therefore, a mage would need (229.5/.4=573.75) 574 spirit to gain the same amount of critical strike chance. (more…)
