By pure kills, yes. But even Davidwales knows that impact goes beyond simple kills.
Do aircraft make GV'ers more cautious by threat of attack? Yes
Do aircraft make perk GV's hang back, or not up, by threat of attack? BIG yes
Do aircraft report location of GV's to other GV'ers? Yes
Do aircraft destroy GV hangers, and guns? Yes
Do aircraft help inhibit offensive action with GV's, through threat of attack, and actual attack? Yes
Do aircraft help a GV offensive by killing the few braver perk GV'ers that venture off concrete? Yes
Do all those have an effect on the GV game? Yes.
Karnak, either you're making a very poor attempt at misdirection here, or you are entirely ignorant of what the game is like for a GV'er. I suspect its a combination of the two.
Aircraft should only die to non-AA vehicles when being shelled on take-off or landing, or when they are being not just dumb, but suicidally stupid. A-20's can avoid deaths to tanks by not trying to fly down their gun barrels. Tanks cannot do anything avoid deaths to A-20's without sitting on concrete or not upping.
You can either solve our bombdweeb problem for us, or solve the larger problem of tanks being unable to defefend themselves before piping in with your uninformed opinion. Untill then, you would do well to remember that your opinion IS uninformed, and that you are speaking from a possition of VERY little expirence.
