I believe I should post this in Help and Training rather than Wishlist because it will recieve -less- people who say 'NO!'.
I think it would help newer players if certain blocks of the training arenas will sustain damage, for example Dueling Zone or Bombing Zone, so people can find the strenghs and weaknesses of planes rather than having to go to the Dueling Arena. Trainers could fly with the newer players and show them how to take a good shot. I know people will think 'they can already fire at other people', but it would be nice to show newer players what they can do with their 'handywork'.
The system would be something like this:
The player 1 would fire on player 2, player 2 would explode to die. Player 2 is spawned back to where he was killed, so he wouldn't have to take off again. Player 1 has the kill like in MA, but no score.
It would be a fun idea and possibly make more people come to the training arena.
