I am starting this thread because it irritates me when a guild comes into a town and starts killing guards.
We should, as players, have the ability to attack anyone who attacks a sided guard. This does not include someone who is attacked by a guard... Only if they attack back.
Example.
I am in Tir. Omnis come to Tir and attack guards. I should have the ability, as a clansman, to attack the attacking Omnis to aid the guards.
