Realistic Helicopter Flight Mechanics and Explosion Area Damage
Add proper flying mechanics to the helicopters instead of that distorted scroller videogame controller mechanic. Much like the shotgun, it makes it too easy for people to hide in the sky and score unchallenged kills, especially since rpgs and rockets can be outrun due to the broken flight mechanics and the lack of proper area damage from explosives. It would probably be good to fix that issue as well. APCs are generally ineffective without nearly direct hits.
In some cases, and impact grenade to the torso does not kill a target, which is also ridiculous. So, feature requests... Realistic flight mechanics and proper area damage for explosions of all kinds.
