User blog comment:AlexHawks/Challenge the meta - Support in the MID lane/@comment-8152061-20130425151012

I've played AP Midzcrank before against Ryze, it was pretty decent. His full combo with a completed Lich Bane is 350% AP (100 from Rocket Grab + 75 Lich Bane Auto +100 from Static Field + 75 Power Fist)

Nunu I believe belongs more on the top lane, as he only has 1 effective damaging spell, and even though it's a 100% AP ratio, the base cd of it is 6 seconds. In a teamfight, you'll probably get off 2, 3 if you're lucky.
