Well God mode is essentially what I was suggesting, but that's beside the point. The way I see this is that it's more for the meaning behind it than the actual implications. This rank wouldn't be different from the current Mod rank. The only thing different is the meaning behind it. PvP isn't the main focus on this server, so it gets looked past and ignored by some, if not most, of the staff. You're right in saying that some of us make rounds, and in the end we all monitor chat and such, no matter what world. That being said, not all staff treat PvP the same. Some are for it, some are even against it. What this rank would do is give the PvPers someone to come to. They could go to this person, and then that person could pass it along to the rest of the staff, and take the necessary actions. This would make those Minecrafters feel more heard, and more a part of the MCA community. Like I said earlier, it would essentially be a Mod rank, and the only difference would be that they are the voice for everyone in PvP. All issues, suggestions, ets., would pass through them, and get filtered through to the rest of the staff.
All that being said, this is just an idea, and one that the current mods+ will have to discus.
