Reposting this from WoWHead -
- MP5 = GONE! Replaced with spirit, which will now be mana regen only—and non healers will have ZERO need for it.
- Spell Power = GONE! Replaced with Intellect, which now grants mana AND spell power.
- Attack Power = GONE! Agility now gives 2 ap for rogues, hunters, shamans, and druids!
- Defense = GONE! Tanks now receive ALL their anti-crit from talents!
- Armor Penetration = GONE! Replaced with "Masteries" through the talent trees!
- Block Value = GONE! Blocks will now be a REAL mitigation stat, preventing a % of incoming damage!
- Soul Shards = GONE! Will be replaced with a functionality more like DK runes, where you can use a "Soul Burn" spell once per shard per battle—and Soul Burn will increase the effectiveness of your NEXT spell a la Amplify Curse. Fears might become Instant, Searing Pains might have free crits, Death Coils might have increased Horrify duration, etc.
- Hunter Mana = GONE! Will be replaced with "Focus", which is similar to rogue energy, but regens faster when you use Steady Shot.
- Hunter Ammo = GONE! Replaced with an item, not a consumable!
I mean, damn, I like it being simplified - but good golly. That is a lot of changes.
