I haven’t run into any matchmaking issues, but I wouldn’t be surprised if the peer-to-peer netcode of the game is a bit fragile, hopefully it will improve.

I don’t think I’ve ever had a gun fail to reload except based on in-game conditions such as being mid-dive, ragdolled, mid-weapon-swap etc. And plenty of times I’ve cancelled a reload by sprinting, swapping, diving or firing before it has finished without realizing.

I’m not sure how any part of the UI is controller specific. Kind of the opposite, I feel bad for console players having to deal with an inferior input device.
