@Jonnio - have you had any weird input issues on the PC version during war stories? Finished the British one at the start and began the Norwegian one. That played fine for about 15 minutes itself and then just randomly, I couldn't scroll through the weapons with the mouse. I couldn't fire either, nor reload which I have set to the middle mouse button. No grenade throws from the side button, yet I could lie prone from the second side button) and also crouch using RMB.
Went over to some dead enemies and couldn't pickup their dropped weapons. The alarm had been triggered and I had nothing at all that I could fight back with - lol.
Jumped onto an MG42 emplacement - fired a couple of rounds and it was back up and working with the weapon selection when I left the emplacement?
What I don't get - and this is a bizarre DICE staple-feature - is why the hell can you not scroll through all of your inventory with the mouse wheel???? Both BF4, BF1 and I think BF3 does it too. You only have four bits of kit anyway and they are all considered as weapons in some shape or form. Instead, you can switch between primary and secondary and then press 3 or 4 to switch to the bits of equipment. Just leave it ALL on the scroll wheel like you did with BF1942, BF2142, etc. I actually think this might be due to console (and by that definition) gamepad support in the later titles. It certainly stutters the fluid flow of the K&M users on PC.
A silly oversight, imo.
