The absolute air-superiority making air-vehicles useless.
There is a way to make every air-vehicle useless in BF6, and it needs to be a priority fix. It ruins the experience for everyone that loves flying Jets and/or helicopters.
Laser designator + AGM/ATGW/Air-to-air/really all lock-on missiles = absolute hell.
Hear me out: As long as someone is laser designating(Sniper class/IFV gunner), you can shoot down any heli and jet without them having anything to do about it/counter with. This works with lock-on missiles from IFVs, Javelins, lock-on ATG missiles from helis and jets.. this is not a problem in its self, and really is a nice feature. The problem is that flares doesnt work against it...warning system? The only warning you get is that you are locked on/laser designated. Yes you can flare this, but you get locked on again as soon as the flares are dropped. If the warning is gone, and you think you are safe? Never mind, a fu***ng javelin shoves your asscheeks up to your uvula after silently following you across the map.
As things are now, the AA-tank and Stinger launcher is the least effective anti-air options.. not gonna lie, ive exploited this thing to its core.. and its f***ing broken. To the ones i have ruined the experience of flying, i am sorry. A single IFV should not be able to secure complete air-superiority.
Ill give you another example. Me and a friend in a heli, using a mountan/hill as cover(to not suffer the same fate) + a friend using laser designator, lasering every jet and heli.. the enemy air-vehicles dies by our lock-on ATGM before getting anything productive done for their team. If not a heli, a squad of 1 Engineer, 1 Recon and 1 Support can obliterate anything that leaves the tarmac.. and your flares are cute and insignificant.
Again.. fix this sh*t.
