Considering one of the main intents of the WW1 arenas is to use them as a defacto test server to test out new stuff before its introduced to the MA, maybe propose that the 2nd WW1 arena be used in the same way but for ground vehicles. This way new stuff intended for the ground portion of the game can be tested out prior to release in the MA. I think there might be a more receptive ear to having a TT arena if there is also some added benefit to having one.
