The low altitude lock block should be removed

Then use rpg's or TOW launchers which hit the heli in one shot kill...

I consider my self a good heli pilot and on maps where the enemy team is scattered and has at least 2 stinger missiles you can't do much... fly low get rekt by atgm's or rpg's (even when flying fast because you have 0 cover) if you fly high one missile misses when you use flares but then you get another one comming just for you ... if you have a problem with helicopters it is pure skill issue since most of my heli kills are from an rpg xD 

I think you got a point, and maybe I was a bit tilted that day. There was a guy running an 80 : 0 on Empire State, and at one point, half of the team was running RPGs and AA, but we never got him because of so much cover (from RPGs) and the low altitude lock.

At the end, I think low altitude lock should stay in the game. However, I firmly believe that urban maps must not have helis, too.
Sure, very good players should have very good stats, but dominating a server like this is just plain unfair and only fun for exactly one person.... I hope you can relate to this 😊 Cheers
