So long as getting TKed doesn't reset killstreak. Or TKing could be taken out of HC

Keep the friendly fire on.

Keep the 3 teamkills and your kicked from the game ala WaW.

Only change I would make is don't let teamkills from Killstreaks count towards you getting kicked.  I can't tell you how many times I was kicked because idiot teammates would run into my air strikes and get me kicked.  You should only get kicked due to kills from guns, grenades, launchers or equipment.  Also, since there is host migration, if the host is teamkilling please let him get kicked.

I would also like to see some sort of punishment like losing CP for those kicked from the game.

I don't want shared or reflect damage.

Definitely make it so you get kicked after X amount of kills.  Shared is just plane stupid... I don't see what the point is.  I think team killing should be kept part of hardcore.  There is a level of skill required to make a quick judgment call between friend or foe.  Maybe you could implement a sort of forgive or punish system.  If you accidentally kill a team mate, he/she has the option to forgive you or punish you and if you rack up too many punishments, i.e. 3, you would be kicked from the game.  If I'm playing with a bunch of friends and a bad nade lands at their feet, they would forgive me and play would go on.  I feel that this is a fair and balanced way of keeping team killing in the game.

LEts Change it a bit, Reflect is simply a dumb idea, if at the end if reflect is the one chosed, simply disable teamkill. It puts me into rage mode when im shooting at some dudes and some stupid team mates runs into my bullets and kill me... when he should be the one killed    . + Whats the point of making people mad when you could simply disable it and everyone is happy?
IMO the best choice would be that teamkill is disabled in the first 20 seconds of the game, then it would be activated but you get killed for n number of teamkills. 





btw DISABLE GRANAID LAUNCHERS IN SnD PLEAAAAAAAAAAAAAAAAAAASE

Reflect or Shared in SnD
