First of all, I'm ms resto, but I go ele for a few fights. I just got http://www.wowhead.com/item=90527 for resto, but I use windsong for resto instead of jade spirit. I'm currently using http://www.wowhead.com/item=86893 for ele, with the gem, and of course jade spirit. So I was wondering if it would be better to use the dagger for ele despite trading jade spirit for windsong since the dagger ends up with a little over 700 more SP, and since I have the heroic OH from feng, I would also get about 120 more int.
What do you guys think?
