Well I'm just looking for a good mouse, main concern is comfort and I'm right handed ATM the Imperator looks nice as macros on my mouse I seem to forget about... But the most important thing to me is confort and shortly after is usability I love FPS and as much as a controller feels easier I hear that mouse a keyboard can let you do so much more, so a great range of DPI is very nice, after that I just need a mouse to make playing my mage on WoW easier I love all my spells and addons help me manage but that doesn't exactly mean i want my mouse to be my rotation or spell book by any means...
Anyway I'm rambling on so now I ask you guys for help, thanks in advance I'll be buying tomorrow.
PS: My mouse pad I'm buying is the Megasoma so I hear going razer with razer is a good idea.
EDIT: On second thought I might wait awhile and get a pair of Megalodons first
Here's a recent mouse evaluation which features a wide range of mice. http://www.overclockersclub.com/reviews/cooler_master_inferno/4.htm Btw i personally use a Logitech MX-518 which is close or like the G-500/G-5. Also have a 3500dpi Deathadder i like them both about the same. The Razer has a better scroll wheel but the MX-518 tracks better for headshots imo.
The Logitech G5 is good, but is made of shitty material. The "painting" on it is getting matt.
