However, now that Int gives you spell power it makes me wonder why you wouldn't just stack Int like crazy.
1. It gives you a healthy amount of Spell Power.
2. Gives you max mana pool to last longer in fights.
3. Gives you mana regen because of Replenishment and various % mana gains.
4. Also gives some crit.
5. Spirit won't scale with % stat increases. And certain masteries/talents scale with Int better.
I guess in my case (priest), I could see myself favoring Spirit alot more than Int as holy, while disc would obviously be all over intellect.
It just seems like Int is a godlike stat vs spirit, it does it all.
