Not a fix but a work around. If you have a Microsoft keyboard like me or another that works with this program made by Microsoft called "Powertoys settings" inside you can use the "keyboard Manager" to bind wsad to the arrow keys and arrow keys to wsad which will allow you to use the drone in game after remapping all movement to wsad which would now be your arrow keys. Javelin anti-cheat is okay with this program running as it is made by Microsoft and cannot be used to cheat like auto-hotkey scripts. (drone movement tied to infantry keys, issue is turn hard bound to arrow left right but want strafe there and when it does both at same time camera go crazy)
The downside is if you chat in game a lot unless you use the arrow keys when typing the 4 letters wsad you would need to disable keyboard manager to chat then re-enable to move, about 4-10 seconds each way as there is no key to toggle it on and off in game you need to alt tab. I assume this would drive a in game chatter crazy, and be annoying if you wanted to chat anything.
