Speaking as someone who lives for ground attack, 190 F8 being my preferred ride, I would love to see something like this.
It does fill the empty position between the M16 and the Ostwind, I can't tell you the number of times I have had a M16 hose me as I bomb the Panzer/M3/M4 he is trying to protect and I fly away to return and rocket him into oblivion and most of the time, I suffer no damage.
No need to perk it and it would cause a change in some of the tactics employed, by some of the players, Low bombers hedgehopping versus 5 or 6 Wirbelwinds rapid fire 20mm guns and the 37 mm of the field guns or Osti's and it may happen less and less, something I would like to see, if you care to know.
