I haven't paid a lot of attention this year, but my list:
1. Cookiezi
2. rrtyui
3. hvick225
4._index
5. Rafis (actually haven't seen much of this guy, but i commend his pp efforts)
6. WubWoofWolf
7. My Aim Sucks
8. Axarious
9. Azer
I can't really give more examples since I haven't watched a lot of professional play in a while. I only jumped the Cookiezi bandwagon when I heard he was back because I know that he's a legend and I KNEW he would hit the top of the ladders almost instantaneously. Also, that Blue Zenith play is absolutely insane.
