The thing is, if you're guaranteed to gain points if you hide while holding down sneak in an obscure corner of the map, too many people would do that. Maybe the majority of players wouldn't do that, and would actively seek out people to fight, but all you need is 2 people doing this per game, and the people who are searching for people to fight will be stuck never finding them until DeathMatch. This would make the game incredibly not fun and boring for everyone involved, especially the spectators.
Edit: And if your issue is that you keep losing points, then maybe you should start killing players. If you can't kill players, then you deserve to lose points, that's the whole reasoning behind the point system in the first place, not to show how well you can hide in a cave or run away from people.
