Attrition. Maybe it's time to get rid of it completely.

Yeah, but you had more of them (launchers), they would recharge (UCAV) or you could pick them back up (T-UGS, SOFLAM, Mortar). In BF4 I had 7 of any launcher, instead of 2/3, dealing more damage on average, with a clear ease-of-use advantage.
I agree that vehicle gameplay does not incentivize PTFO, but AT ranged capabilities are non-existant outside of the rare AT-rifle user that is not choosing the weapon for the OHKs.
