As of 2 days ago i was about to buy the razer naga, until i done a bit of research and found out that the buttons on the side are just another way to press 1-9 on your keyboard and i feel this is next to useless, i would much rather have seperate keys on my mouse that i can bind to buttons out of the W zone of my keyboard i love using my mouse to put all the keys i use most often in arena so i thought a naga would be pointless for me apart from the 2 badly situated keys at the top that are extra keys.
So instead i brought a razer deathadder respawn as i did currently own a deathadder that was abit worn and torn, it arrived today and its fantastic. I seriously would not be able to pvp without a mouse with extra buttons for example i play mage and have. Sheep = Press mousewheel in. Counterspell Mousewheel down. Cone of cold mouse wheel up. and the other 2 buttons on the side are bound to both ice lance and blink. All the buttons i use most on my mouse. Cant sing this mouses' praises enough!!
