I'm cracked now I went 9-0 last night, 3-0 in ranked, and 6-0 in br. Getting a monitor is the best thing you can do to play better. I've never made WS or gone 12-0, but going off of the way I played yesterday, I think a monitor could break that wall for me!
If anyones wondering what moniter, its and ASUS VG245H (about $160)
