Lis is useless and pathetic now

The problem with Lis is that the tgm is supposed to be vs both air and ground. Its literally impossible to balance that out without either nerfing heli maneuverability big time or making tgm super op vs ground. Its like trying to make someone be both the worlds fastest sprinter and the worls fastest marathon runner at the same time. It wont happen.

Saying they added skill to tgm vs air is wrong as the "skill" now is simply whether the heli pilot is skilled or not. Any skilled heli can and will dodge tgms all day long. However unskilled heli pilots who just float in the air are still easier targets but you could do the same with recoilless... In short its just luck based depending on who pilots your target.

Vs ground tgm will always be somewhat op as ground doesnt have the luxury helis got.

One solution could be the same as you have for Sundance. 2 versions of tgm. One with better maneuverability vs air that does 0 dmg vs ground vehicles and 1 with little maneuvaribility that does dmg vs ground but 0 vs air. Then balance in some switch timer.

Another solution may be to leave the tgm where it is vs air but increase the reload rate and nerf damage (make dps the same) vs ground. That way you can shoot vs air a little more often and maybe luck a shot in while you will need more tgms to take out a ground vehicle. 

Of course a third solution is that Dice fix the fxm balance, do something about the constant lack of resupply options and makes the other engineers a viable option as well.

Not saying any of these is a definite fix but doing something new is way better than trying to make a square fit in a circle and a triangle at the same time.
