"Ks'ing" is not kill STEALING... It's kill "Sharing".

It wasn't your map before you got there
It Isn't your map while you are there
And it wont still be your map when you leave.

According to that logic, you can throw a kid out of a swing, because the park is "free for all". You are supposed to wait until the swing is free and not to be an ass.

This game is not about dmg competition, if you wan't to be an ass and ruin the game for others... piss off.

I would find another MMORPG (free) to play.

I hope you do, and take other ksers with you as well.
