Being a Disc Priest I'm all about mp5 gems and sp gems. Was looking at the top Disc Priests on my server and a few of them are gemming straight intellect. I'm reading everything I can find and I'm not entirely sure why they'd gem intellect. Yes more mana is great but I love my mp5. Of course I'll stay with my preference but I'm really curious as to why to gem for so much mana. I can't find any info as to the benefits other then a larger mana pool. Their stats are the same as mine (crit, spell power and haste) only diference is they have more mana and less mana regen.
Sounds stupid and I should probably know the answer but I've tried to find answers on my own, I just can't seem to at all.
