Pretty sure I didn't see this listed in this topic (altho i did not go back and read the other topic that was linked). This has to do with Keybindings. Currently your are able to keybind mouse buttons 1,2,6,7+ For some unknown and confusing reason we are not able to keybind mouse buttons 3, 4 or 5. Why and how did it get designed as such? I can have lmb and rmb plus any button above 6 keybound? Why is 3,4,5 skipped? How does that make any sense? Now I'm no programmer, but I can't imagine that this issue cannot be resolved with the next patch.
