Razer still makes the best MMO mouse you can get your hands on.

Razer makes a ton of different mice, but one of its most iconic lines is the Naga. The range began life in 2009 as a dedicated mouse for MMORPG players, right in the middle of World of Warcraft's heyday. Its 17-button layout, with 12 side buttons gave your thumb access to keybinds for actions and abilities, was utterly unique at the time.
