Tanks carried spare parts on their hull, right? Why not make one of the ammo options for the Panzer less shells and one cargo?(supply).
I do it all the time, up a hurc where there are tank battles, drop in on top of the tank, aim, quick 3-4 round burst, no turret. Spindle can't hit you at that angle, and if you hit it is more likely to be the turret. He ditches, easy kill. An eight kill run(panz alone) is not uncommon defending a field. Just don't make a pass where the spindle can hit you head on.
I know some will say you shouldn't be alone. Or you might say bring an m3. But getting someone to tag along in an m3(target) is a tall order and they are usually down b4 you get a chance to use a single supply, and sometimes you come into the arena with short time and want to get in some action. It would also give an advantage to the people who are organized.
Also, you won't hesitate to up a tiger to defend, but if you haven't got a thousand gv perks, you can use them up pretty fast on offensives. It's alot easier to get someone to tag along with a panzer than an m3 for sure. Maybe instead of flak offensives we will have more tank offensives.
In the end, the m3 is the way it should be, but you can't camo the m3 or hide it under some trees. And the ICON doesn't help either:lol . That is why I think this would be a good idea.
