Not really a bug but having ctrl + shift + d as the default deafen hotkey is stupid. (Anyone who plays FPS games will agree)

CTRL + Shift + D is the default deafen keybind which I painfully realized while playing deadlock and moving about ingame

Play any game that requires WASD movement and uses ctrl for crouch aswell as shift for sprint or dash and you'll see why this is a bad default hotkey
