I think, that ArmA 3 should get something for the pilots, too. So you have to learn how to fly, instead of just taking off by pressing Q. If you look at the game Take On Helicopters, the take off was much more complicated. Is it possible to convert this to ArmA 3? Oh and it would be really nice, if you could improve the physics for helicopters, so you just can't make a barrel roll with a Little Bird.
It would only improve the gameplay and I know that ArmA 3 is a simulation based on the infantry, but why don't make it a complete simulation? Or at least removing the ability to make silly stunts with an attack helicopter.
