well if its not the best, it certainly is probably in the top 3. depending on how you play, intellect can be > spell power. example is my paladin. I spam Holy Light just because every single enchant and gem I have is Intellect. Raid buffed im sitting at 1600 int while most other pallies are at 1300-1400. There is lots of overhealing with this gem/enchant choice, but you never go oom and you're usually in the top 2 for healing.
If anything rate 30 int to wep higher than a 3...
