My view, without getting technical, is that physical prowess should over power ranged magic/ physical manipulation just to prevent early OP. 

I imagine it would just feel like walking through a wave. Don’t get me wrong, a wave can push you back, but then you would be throwing the water to make it stronger. I also imagine the water source is limited.
In the air the water would have the advantage but on the land, with its many legs, I would give it to the bug.

Ultimately up you you guys and Rai tho.
