I've seen more p47s kill flaktraks then the other way around.
Yeah, that needs to be adjusted. I feel like Relic wanted to express air intervention in this game, but it doesnt seem to be any more expanded than to come in, kill everything and leave - for a simple munitions price and a click.
When i bought this game November 2013, i was under the influence that air combat and support was a big thing (stressed in the Steam video introduction). Upon the development of WFA, air support was severely stressed again (loitering). However, i see little depth with planes and their jobs and counters.
