Another vote for the g600 here. The mouse is HUGE and not anywhere near as comfortable as the older Nagas, but I went through 5 nagas, a lycosa, and a headset in a period of 3ish years and replacing 1.5 devices a year is just too much. Logitech is a more solid brand and I replaced all my Razer gear with it. I arrange my hotbars stacked on top of one another and changed the keybindings to mimic the shape of the numberpad to help visualize where my thumb should be for each ability. With shift and alt modifiers, you have 36 buttons at your disposal and you never have to move your hand from the home row. It's great.
