buttons spread out, 1 hard to press, buttons stick

i've used a naga 12 button for many years. sadly it finally failed, and the original naga cannot be bought anymore. My main issue with this mouse is the buttons being diagonally set. therefore, if you have the buttons in any forward position at all, your thumb will likely drag on your desk while pressing the 1 button. I have pretty small hands and this is an issue for me. also, i feel like the buttons should be closer together. I feel like with this mouse can you either each the front 9 or the back 9. also my - and = buttons stick randomly. I would've returned if there were many better options out there.
