1) Show the timer on when you'll be reved - I don't want to just stand there and watch the person who KO'ed me with their Gran Faust and stuff.
2) When a knight gets killed, don't make the camera follow them - It just ruins the point of playing LD. I KO someone with my Gran Faust. Cool, but now they'll just track me down quicker. Instead, it would show the knight's name and you would only see the lockdown lobby. There will also be tips while you wait.
The respawn timer is very nice, but I'd like to get the audio cue back instead of the timer. It's five seconds of beeps. You respawn on the fifth beep.
I agree with #2. Either have the camera switch to a teammate while waiting or do what tf2 does-- panning the camera for about a second towards the killer and insert a freeze frame.
