Guild Wars 2

Does anyone use this to play GW2? I currently own a Razer Naga. I’m not entirely sold on the 500. I feel like losing buttons would suck.

Not sure about the Rival, but I can definitely recommend the Logitech G600. Used it for most the time I’ve been playing this game and never had any troubles with it once I got used to it.

I don’t think you need to be concerned about losing buttons. The Rival 500 has 5 side buttons, 2 on the left side of the left mouse button, 1 on the right side of the right mouse button, 1 between the left and right buttons and a tilt wheel.
