I'm a casual WoW player and am looking for a new mouse, I read PC Gamer recently and saw the R.A.T. 7 and thought it looked good. Everywhere I look however told me how great it was with a FPS, I really like this mouse but need to know if it works okay with WoW. Basically that the buttons can all be macro'd to WoW and if it is worth the $100 price tag. I also play some FPS's like Crysis so the Sniper mode won't go to waste. Let me know if you have any experience in this area, Thanks!
