I think it's a fun feature, it's extremely satisfying to hit and it's funny to be in a full passenger heli and start spinning out hearing the game chat
But it's too easy to hit to the point that in certain situations the vehicle is just a free kill with 1 HP.
I think it should stay in the game but be harder to hit so it's more skillful or more random. At the moment BTR/LAVs are basically a death sentence to a transport heli when they already do some huge damage just by hitting it normally with the shells
