Why would I want to play against a player with level S690?!!!

@ThePla7Maker Sometimes, but not often. I cannot avoid the helis and armor, who will ignore the entire battle around the objective and will chase me across the map just to kill me.
As for the high kill players on foot, my death cam allows me to watch these guys for a brief time, and they are standing in the open just blasting away and hitting everyone, sometimes at a dead run. I was killed twice by someone who was actually invisible, only thier name tag in red showed up where they would be standing. At first I thought they were in a bush, but the second time it was in open space.
I never had these issues in BF2. Of course there werent consoles and we were on a level playing field with servers we hosted and controlled.
