Game is broken or what? higher grounds do MORE damage than Lower grounds.

high ground is a positional advantage in games and real life. ask Anikin.

You''re just a noob. Higher ground is just positional advantage.

It's easier to hit opponents from high ground due to the view angle. Also if going for headshots it would be easier as well as you don't have to compensate as much for bullet falloff.

Highground = easier headshots

Above angle drops headshots closer to center mass. 

in all video game's higher ground is better it's a tactical advantage over your enemies. It deal more damage because your hitting your enemies in vital spot's that deal more damage [head shots and back].

The game is not broken it's just your team was out maneuvered and you lost because of lack of aim, positioning and understanding where enemies are.

If some one is on the hill just walk backward while taking pop shots so your target bullets deal less damage the farther you get the less damage bullets do. rush if you can or take cover and fire back and never show your enemy your back while in a gun fight [ at least try not too].
