The BEST role for Varus is as a poke mid
If you disagree with this, you should post a statement, or question, and I will try to respond with my thoughts including build questions. Don't mention his lack of escape as the reason he cannot mid. I am saying right now, THIS IS HIS BIGGEST WEAKNESS. But that does not mean he cannot/should not go mid. There are plenty of mid champions that have no direct escape. Xerath is amazing mid right now, he has no dash/jump/movespeed increase. If you want to know specific strengths, please, ask me about it. I firmly believe this is his best role, and he actually fills a very unique spot right now that shuts down a lot of common mid picks.
Is typically a great build for some burst with your basic attacks while still giving you a lot of possible poke damage.
