My eSports gaming mouse. Gotta have those extra buttons, man!
Being on a Mac, I can't really work without a... well, it doesn't necessarily have to be a gaming mouse (though I'm currently using a SteelSeries Sensei and was using a Naga before that broke), but certainly some sort of multi-button mouse. For WoW specifically, a 5-10-button mouse is ideal (and even more ideal is having buttons on both sides of it). I don't think any company currently makes THE ideal gaming mouse for me, though the SteelSeries wow mouse was pretty dang close (if only it had worked on my OS!).
I could not live without my Mad Catz M.M.O 7 mouse since i have so many key binds attached to it
I love my Razer Naga mouse. It's gotten me through lots of late night gaming.
This may be a "duh" answer, but: my keyboard. So many games require extensive use of the mouse or even a gamepad, but I like just playing on the keyboard. The mouse is for aiming, selecting and that stuff, but the rest I preferably do with the keyboard :)
My Steelseries Sensei has served me faithfully for a while, but it is in need of replacement these days.
My basic mouse - Logitech M705.
I couldn't live without my Razer Naga.
A good mouse! I currently use a G400s on my desktop and my old G5 with my laptop.
My steelseries diablo 3 mouse
I use the Steelseries WoW mouse Cataclysm edition and I too wouldn't know what to do, if my mouse breaks. Hopefully that will be in the very distant future.Next to that my Beyerdynamic DT 990 PRO studio headphones.
I love my Sound Blaster Tactic3D Rage wireless headphones so much because they sound great, are comfortable, and let me holler in vent as need be to keep stuff organized lol
my Logitech Trackball....I used to hate trackballs, but that was back when they were controlled by your index and middle finger instead of your thumb....now, I can't do without it. Moving and targeting are a whole lot easier when you only have to move your thumb instead of your whole hand, not to mention I can use it in my recliner without having to reach for a tray table...lol
My Logitech G9X has lasted longer than any other mouse I've used and taught me how valuable 2 extra buttons can be on a mouse.
My Logitech g600... Will never play without it!
MY MOUSE, my hand.
My naga is the best mouse I've ever had, it fits so perfectly in the hand. Also I've fallen in lovw with my new Blackwidow stealth!
Can't live without my Razer Naga mouse :)
to be honest I have been playing with standard peripherals for a while but once I gave in and bought a Razer Blackwidow Ultimate and ever since I can't even think about getting rid of this keyboard ever.
Loading screen bosses are the worst, thank god I've geared myself up with couple SSD's. #ThingsICouldntLiveWithout
