So it's giving Allies a headache not to be able to use all that stuff with impunity. That doesn't mean it is unbalanced as such. Make a decision if and when you use a drop. Maybe occupy the Flak HK with a tank meanwhile? Or take it out, it is not indestructible. It can as well become a liability in the wrong place where your pios are repairing it more than doing anything else.
lul, but aside from funny arguments, do you have some intelligent ones?
Now about your idea of removing Lt/cpt/Major from teching, Australian and Katikof are right, that would actually become a boost and new strategies in some aspect of the USF gameplay, even more with the new mortar. And I'm only talking in its formal state and prices.
But if we are at removing factions things from teching because that's the only base on your defensive argumentation, how much do we price everything Ostheer get with teching cuz, LMG/pfaust/grenades unlock are actually as free as lt/cpt/Major and bring as much as powerlevel to Ostheer T1/T2 .
