I recently completed 9/9 gold for the first time on my mage and now I'm looking to do them on my Rdruid. I've done a bit of research and I'm still confused on whether or not I should gem/flask int or spirit. Just before the servers went down I managed to put together a set with mostly spirit and gemmed/enchanted pure int. I figure I'm going to be healing my ass off and drinking all the time so stronger heals would take precedence over mana regen, that being said I never really had time to observe the healers in my groups so it's hard to say. As far as reforging goes, I went with haste > mastery with the exception of spirit on pieces without spirit.
I'd love to hear from people their experiences with different optimizations and how it went for you and whether or not you feel it's the best option. Any tips/tricks in terms of glyphs/talents would also be great. Thanks
