Why not Ziggs support?
The reasoning behind the recent Ziggs bot lane fad is his ability to first blood tower quickly with his passive, W and LB so wouldn't this also fit with Ziggs as support without losing your late game carry? Ziggs could Q the wave and let the ADC clean up for quick pushes, Caitlyn preferred I would think, and just keep putting damage on the tower until it goes boom!
I think I'll try it, most likely maxing W first to lower that god awful CD. The ADC would have to assist with early wards though and we know just how much they love to do that :P
right now and Ziggs wants heavy AP.
