I'm not even sure why they added vehicle abandons. It makes driving nearer to enemy territory more dangerous and rewards more boring, cautious, campy play styles.
I don't agree. Yes going to the enemies territory unsupported is now more dangerous but for me, it gives an adrenaline rush whenever a vehicle gets abandoned. To quickly destroy it before the enemy gets it or to quickly rush my infantry there for recrewing
It doesn't punish players who support their vehicles, which is a good thing.
