Currently Gnomes have a 5% intellect increase as one of their racial abilities. I have heard this will change to a 5% increase in mana pool for Cata. As a dps caster, I am considering doing a race change to take advantage of the 5% intel but if this changes to mana vs intellect with Cata then it is not worth it. Maybe for healers...
Found this on wowwiki:
Gnome
Expansive Mind : Increase mana pool by 5%. Change to mana pool from Intellect occurred with Cata.
Can anyone confirm? Thx
