This is a new game and as such will attract a new player and most probably anyone that has played a FPS that wants to try something different. Well in other FPS's the aim of the game is to run, bunny hop and kill as quickly as possible and tk is meant to be fun.
We already saw this on the release of the German version but in a small scale but it can really ruin a server, I suggest that servers have admins at all times ready to perm ban the kiddies that wish to 'test out tking skills' in game.
The BF2 crowd will be all over this because it looks nice, also the CS crowd will jump on baord hoping to get some CS type action out of it... we know it doesn't exist so in a week or 2 they should get bored and go back to their BF type games give us the occasional appearnce to test the admins.
I do suggest that TKing at any base or spawn gets a perm ban from your server as they will not learn and come back as 'it seems like fun'.
Good luck to server admins and players, please keep your cool and continue to try and play whatever mission you are on without retaliating.
