I've been reading this thread since it started, and after some online and offline practice with the game's tankbusters I've reached a conclusion. And it's probably entirely wrong, but bear with me
.
Tankers want to be left alone. I've experienced this many times, as I was driving my purty Hetzer and got hit by a Lancaster's bomb which is probably bigger than my toy tank. But it's ok, I die much more often by the hand of another tank. It's rare enough to see a tank buster, but if he's attacking you can simply ping him to death with the AA mount (yes, most tanks have one of those!) or main gun him if he gets close enough to really hurt you. He won't see you until he's really close, but you can be tracking him with your turret as soon as he enters 6K.
About the GV killers:
Il-2: great against Panzers from the rear (and close), M3 and little else. You can bust some other tanks hitting engine compartment/turret from the top, but it's quite tricky in any substantial dive. Quite suicidal on a moving target.
Ju-87G: will bust most things from the side and rear if you shoot the armor at almost 90º and under 100y. With flaps it can turn a little, so it'll probably take a fighter two passes to kill you instead of one
. Don't chase a Jeep, they'll outrun you.
Me-410: yes, it's a dog. Yes, it handles like a pregnant whale. But it's got a big gun which can pierce a Panzer or any Sherman with a single shot to the side, and any other tank hitting the rear/top. It also can make 318mph on the deck carrying the Bk5, and has dive brakes which help a lot when attacking the top armor.
Is hitting an attacking airplane with your main gun gamey? Yes, totally. But it's done very often because players can exploit the commander position. Some tankers will argue that otherwise they're defenceless. Well, aren't all the attack planes I mentioned sitting ducks? They won't survive a minute without air cover. I personally think that we should keep the commander position, but players shouldn't be allowed to shoot from it. GVs already have reduced icon range, what else could they have? F3 and turn it into WoT?
If we want to kill tanks without resorting to bomb****ing, we have to get someone to make an effective air cover. And even then, nobody can protect a plane from a tank main gunning him. Why shouldn't tankers have to do the same? You're being attacked by a plane? Well, some of your 8 squadmates rushing the VB with Panzers just up a Wirbelwind and he'll be gone in a jiffy. Or, you know, use the AA mount. AA...what could it stand for? Anti-Aircraft? How silly, that's the name of the main gun!
Those are my two cents. I think we shouldn't be able to shoot from the commander's position (it wasn't made for it), or we'll see more and more Lancasters carpet bombing from 1K feet.
