Best Enchants?Follow

Hi all,

When it comes to enchants, what is the best one for the part of the armor? Though my search for info was admittedly short, not a lot is mentioned about it......at least that I could find. These days, there are a lot of possible varieties and it is not such a simple question anymore. One could easily say that an enchant that adds mana or spell damage is good....but is there a preference. Both have advantages, after all, and it might be time to "re-tool", so to speak.

I don't PvP with my mage, so think of it as coming from the perspective of a lvl 70 raiding Fire Mage. Thanks in advance.

Thanks!!
