Since the Velkoz discussion is on

Let's brainstorm what he actually does, shall we? I need you guys's help (Vel'koz mains pls) to know what you feel his niche is.

1. Angles. Cool trick, nothing to say really.
2. Cracks on the ground. Eh, this one could use some change. What does it do except minor zoning? Maybe a bigger second proc would make the zoning stronger, but is he supposed to zone? What if instead it became his guaranteed damage skill? Is that something h needs/could use?
3. Self-peel midranged knockup. Not bad.
4. An ult between Xerath's and MF's. Not as teamfight-y as MF's, since it's much narrower, but still a long line, slowing, and applying passive which is great against tanks in a TF. So I was thinking: what about making his rol in teamfights to get down as many passive procs as he can (thus tankbusting)? And this would be done through higher tickrate, no slow, wider ray. Else we could have the ult slow everything in a large cone and be able to move more quickly above that cone (for squishie hunting). Or it could cleave magic resist for teamplay.

So what is he?
