As someone who is rather fond of killing gv's, in my opinion wirblwinds are highly effective making light work of most planes. In the hurri2d i have to fly within the effective guns range to visually identify it and routinely take hits doing so. The only thing i think which isn't in their favour is f3 mode in bombers which makes it easier to bomb gv's, i think may be the reasons the a20 is used so frequently to kill gv's.
And, you know... The 225mph speed advantage you have. And the fact that you can maneuver freely in 3 dimensions. And that you can grab ordnance to guarantee they die.
Yeah, if you take the derp planes, you will be killed a few times. Expect it, because that's as it should be. But those GV's have numerous aircraft after them, and often times die when you don't see them die. It's not at all like they're invincible.
Besides that, what exactly do you propose be done? Change the view range back heavily in favor of the aircraft, so you can slaughter tanks more easily? I'm still going to plug you with my ostwind if you're dumb enough to fly a straight line within 3.5k of me.
Karnak, aircraft still interfere with GV fights, even if it's not quite so bad now. Having things go the other way a little bit is not a bad thing, since aircraft hold all the cards, if the player makes even the slightest effort to use them. The GVers shouldn't be punished for the ineptitude and laziness of some of the would be bomb tards.
