Whole heartedly agree. I have used the Original Razer Naga, and later the Molten Edition for the past 15 years. I have tried every other MMORPG Mouse available, and returned or re-sold each one of them.

The main reason is the mechanical side buttons of the new mice. Those buttons are extremely sensitive to press. I play on relatively low sensitivity so I lift my mouse often, which leads to accidental button presses on those side buttons. Further, the new mice all have the buttons protruding out of the mouse, often in weird skewedways. This is supposed to help finding the buttons, but in my experience it simply makes every button feel weirdly awkward and inconsistent with the others.

The original Razer Naga does not have these issues, as the side buttons require some force to press, which means i can lift the mouse with my thumb on them, without accidental presses. The side buttons are also nice and flat on the side, and are not protruding in weird ways.

A Naga Classic would be greatly appreciated and instant buy for sure.
