@TTZ_Dipsy The solution to the railgun tank is another railgun tank, as which one spots first and shots first gets the kill. I think Dice needs to leave it be for the moment as it takes a long time to recharge rounds and takes forever to get out of the "low rider" mode and flee an attack. Also a good stealth heli pilot can take it down before one can activate the APS.
I too played Official All Out Superiority and got to T3 (720 kills) on the railgun tank in a single night and I don't normally play tanks. Easy to get 40-50 kills round when there are only 3 other humans on the other side late at night, and every air transport is full of 4-6 A.I. bots that love to hover for easy tank shots. The only A.I. that can actually kill are the WildCat and LIttle Bird A.I. pilots, which is interesting as both these vehicles are completely OP when a really good human pilot operates them...
When the Superiority game modes (All Out and Air) have 100% humans, those 40-50 kill games turn into 10-20 kill games at best.
For some reason the A.I. in BF 2042 have IQ 40...¯\_(ツ)_/¯
