Friendly fire, problem or not?

[Krawanan]

Hey guys,

I think that friendly fire is a great addition to the game, since it makes it alot more real, and you have to be carefull where you shoot.

But i also have a few concerns about this.

How can you see if someone is on your empire in night time? From close it would be pretty easy, but if he's like 200 meters away you see him as an enemy, if FF would be off, you would find out soon enough ofcourse, but it is not.

And my biggest concern:
TROLLS

Aren't there going to be people who like hate an empire and then make a character on that empire just to team kill? Or just trolls who will do this for no reason.

Does anyone share those concerns with me? Or is there already a solution for this? And how did this work out in Planetside 1 ?
