Recently on the DU4 HeavyMetal server, I saw a RU player endlessly firing a Mi28 nosegun at US helis while he remained parked on the landing pad.
This was going on for a few minutes when a US pilot finally got fed up and killed him after being shot.
After doing this the US pilot was immediately kicked and threatened with a permanent ban.
You need to come up with a better solution for baserape prevention.
As it stands now, you are encouraging players to camp in their own base because the enemy is not allowed to kill them.
Not only is this grossly unfair, its downright stupid.
You need to change the punishment to a temp kick at most because perm banning players for defending themselves is utterly retarded.
