[Deadlock]

Options:
1. Xp loss
2. Weapon lockup for a set time
3. Ejected from battle zone for set amount of time
4. You become red flagged after awhile (target for both sides in a battle)
5. Health loss, twice amount as you do to your race mate
6. Rooted, frozen in place for set amount of time
7. Blinded for set amount of time

Many of these solutions would also really damage a person who accidentally kills a teammate while trying to help him. (option 2,3,5,6,7)

Option 4 is a good solution yet I can imagine the community instantly shooting anyone with a red flag to avoid getting shot themselves since there's no way of seeing it was intentional/unintentional

That leaves option 1, XP loss. If you unintentionally kill a teammate you wont be affected by it that much if you just watch your fire, while at the same time ppl who continuousely teamkill will most definately feel the pain

To avoid ppl making a 'teamkillaccount' there's also another option of seperating free-for-all games vs clangames, for example: If XP loss isnt severe enough perhaps a line should be set where as you dont get negative effects while shooting clanmembers and you do when shooting random teammates. (That doesn't make it better for friends who play for different clans tho).

In fact, perhaps Xp loss above (for example) lvl 15 while other measures apply under lvl 15 would be better. The cap should be set on a level where it takes some effort to get to.
