I personally think that even if the current situation isn't ideal, it's better than the heavy tank stalling meta that we've had over the last year.
Oh, definitely. The current system is an enormous improvement over what came before it.
A potentially novel solution:
The T-34's Ram ability has a mechanic where, if the target already has Engine Damage, it inflicts Engine Destroyed.
What if we extend this mechanic to normal snares? If you snare a vehicle that's already Engine Damaged, you inflict Engine Destroyed. (or a less extreme crit like Engine Overheated or Crew Shock).
That'd add a significant weakness to overreliance on a single vehicle: a planned ambush or infantry flank can mobility kill it, allowing you to fight it with anti-tank guns.
It'd also
really help Ost in early-mid against lights.
