So after years of playing WoW, and with GW2 just around the corner, I have decided that I want to get a MMO mouse. The extra buttons are just too much of an advantage to ignore at this point. I've narrowed my choices down to the following, but I would love some input from those that have used them in the past. Feel free to recommend something else, but please keep it under $100. Razer Naga- my only issue here is that I had clicking problems with a Deathadder in the past, and it is far from an uncommon thing with Razer products Corsair m90- build quality looks to be fantastic, but I've heard terrible things about the software. Have they fixed the push-to-talk issue with the mouse yet? Logitech g600- newest mouse of the group so there's not a lot online about it yet. If anyone has any experience with it I would love to hear it. Thanks in advance!
