I went out and did a few 1v1s and I had great success with Gambler against Black Arrows, it wasn't even a contest no matter the rank. But against all the other creep classes it was a lot more difficult, I couldn't find a Defiler but my fights against the WL were pretty equal until some gankers came along. Warg was easier in red than blue and I had trouble finding a high ranking solo reaver. I'm still not sure which line I want to use and I have yet to try yellow yet but we shall see.
