I think Kha'Zix can go bot lane and do decently there

And here's why...

So I've been playing Kha bot lane lately and it's been pretty fun. He has the Q for easier last hits, W for better sustain, E to get out/in, and an R that turns you into Vayne. Plus, that passive Q hurts a lot of ADC who send their supports to do their dirty work of initiating while they stay back.

Also, his core build is pretty cheap - , ,

As an aside, I get a tear on first back to make use of the fact that Kha's Q will stack tear.
