I see lately some level 70 players from the opposite faction roaming in the main towns and killing all NPC in sight. This is easy considering most NPC are level 50, the guards are 52 and the level 70 players don't be present there usually.
I suggest making all NPC in Meridian and Sanctum = max. level in the game + the guards to be elite. So it will be not so easy for some bored people to feel godly.
