I do agree with the archangel's staff choice-- you can get a ton of extra max mana from it by late game-- but alot of your sections were directly copied from Dan Dinh's solomid guide. I suggest you at least give him some credit, as you did put in some new points, i guess...

your archangel is WAY too early. you dont have that much mana so you gont get that much AP at the beginning. I didnt try it but thats pretty selfexplanatory
