I used to play on a lot of kz (climb) and bunnyhop servers when I was still really into Counter Strike, but I was saddened by the fact that I couldn't actually do anything with my movement skills outside of kz/bunnyhop/surf servers. In competitive CS:GO, bhopping is very harshly restricted and there are only a few useful jumps you can pull off in the current competitive maps. I don't remember how I heard about Reflex, but once I saw a video explaining the movement system, it went instantly into my to-buy list even if it was just to jump around on a local server. I don't have a huge history in Arena FPS games and this is the first real entry for me to the genre, and so far, I'm really enjoying it. I just wish I had discovered it sooner.
