I understand you frustration, but you need to flank them and kill them with the hammer or with the knife...so you can humilate them...I do that always hahahaha 

At it's core, Battlefield is a game of king of the hill.  You are SUPPOSED to hold positions.

If you want a game that is just sprinting around like a madman, CoD makes what you want.

It's a boring play style - imagine every player did that. Anyway - you cannot do anything - that is a playstyle some have. The recon class and the spotter thing you put on ground is a good way to tell where they are. Move slowly and not run like crazy - stealth approach !
