Then those things we mentioned aren't working well enough as AT, because they're supposed to be used for AT. Some of them simply cant be used on inf, for example - the AT nade and faust.
Surely that's a problem that you've identified here? That people can't rely on the AT tools they have at their disposal?
They are just abilities, not serious AT. They are snares.
It's ridiculous to expect some ability like AP rounds to be an end-all be-all hard at-counter.
