I say we should not implement a system. It is very limiting to a site like this. I believe you should just make sure people know an respect how powerful others are. If you are a third seat (with third seat power). You would not be able to take on a captain levelled opponent. It is not a power system, but a trust system that should be closely watched by the staff. You know how powerful your character is, train and reasonably grow your power. Power systems are to restricting.
