Medics are the key and there are problems throughout if you analyse it often enough.
I agree with you Lazy on the "Too many snipers" scenario. A class limit vote should see how the land lies with most of the players on the at the time.
I see no skill in standing around "waiting" for someone to pass through a dot to be headshotted.
Yes, I play sniper but generally to assist the team. If only to try and distract opposing snipers or to make distanced targets easier to kill with numerous body shots. For those that laugh at lesser skilled snipers.. think again. One body shot and an alternative attack from another team player normal see the demise of your opponent. You don't tend to last long with less health
As for the +1. I'm not too bother whether it stays or goes. I think it's there to make "em" feel happy about taking part and being higher up the points chart. It wasn't all that long ago when I read that most FPS games want you to make more headshots as this decreases opponent health more than hitting any other target. So in that vane... EVERYONE should be making headshots with any projectile weapon were possible.
