Your concern for the other members' safety is something I certainly can relate to. I'm sure no one would object to your proposal of more training. But any one of us could encounter something we are unprepared for or unable to fight, given the wide variety of worlds we come from. Even the most experienced and powerful of us.
I'm sure you can understand why I feel that members should self assess, to some degree, their preparedness for patrolling, or at minimum be given a chance to prove themselves. If there isn't mutual trust in such an organization, it will crumble.
