Alright, I give up. I'm not making any headway with you.
However, I leave this thread with this closing statment:
Tanks are meant to be used offensivly, and bombing has killed that in the game to a large degree. A reduction or removal of perk loss from deaths due to bombing would help, as would the ability to land at a designated area near the spawn, to borrow another's idea.
That said, there are several ways to fix or reduce the bombing idea, all of which you have tried to shoot down with arguments that have relativly little to do with the game. For example the issue of tanks out in the open is a rather small issue due to the over exagerated ammount of (ineffective) cover.
