So 2% int is better than 2% intellect is 2*67, or 133 int. This works out to a buffed intellect of 6666. Not remotely obtainable. Even if you think mp5 is terrible for priests and say that 1 mp5 = 1 int, then 2% int isn't better until you have 3333 intellect buffed. If you are considering any other metagem, consider [Revitalizing Skyflare Diamond] if you don't have mana problems.
