After playing with the game a bit, I have found keybinding to be quite challenging. Unbinding keys is unintuitive, rebinding does not remove other keybindings, keybindings are scattered across multiple pages, and changes are very hard to coordinate. AND mouse buttons (side buttons) cannot be programmed.
Also menus lag and stutter the game? Not sure what is up with that. Overall, really enjoying the game. But would really like keybinding and menus to not be so painful to work with.
