Rengar
The Knifecat
If you'd also look at the scores, most of them I dominate my lane. I have trouble with positioning in the late game to effectively carry. I need to work on my skills with him, but then again I can just main Rengar for freelo.No, no you can't lol. I'm looking at your match history and you lose games against people your own elo and even a bit lower.
I'll admit, there are the recent games where I've been on tilt (not only with Azir, but even with my main). Azir is really easy to use against mid-elo players. They can't deal with the poke from his q/autos unless they're playing a champion that can trade back.
