Corwyn Draenor:
Don't change for my sake please, play what you want. The magic system is broad enough to allow for multiple wizard types in the same party :)
That's for certain.
But, just to be sure, let's check what scho... er, lores we are all looking at. Ahvylyn will have none of the combat lores, mostly support stuff. Detections, Illusions, Sounds and light, and that sort of stuff. Oh, I plan to spend a point every level in Animal Movements. I am still debating Skirmishing Mastery. But it is mostly archery and I don't care.
We may be hurting if no one tanks though...
