Quote:However, even with your less restrictive idea, that still prevents people from RP'ing previous timelines with players who have already ran through it.
The solution to that is to not have an actual piece of the main storyline as part of your micro-canon. The game might force a certain line of events when you play through content, but there are ways in which you can handwave, reinterpret or ultimately completely change it for roleplaying purposes.
For example, let's consider the Sastasha dungeon. You can easily ignore the in-game information and simply have an IC run of it as if it was just one of many pirate hideouts. If you run the dungeon IC and also using the storyline proposed by the game then you are effectively, as you say, preventing other people from doing that content as far as your micro-canon is concerned.
If you transform the content into a 'generic' version, however, you don't. You can in fact run Sastasha in-character as many times as you want because, as far as your micro-canon is concerned, you are raiding pirate hideouts that are unrelated to the game's storyline.
Quote: You do seem to be comprehending it as though I am implying the the leaders have full control over everything you do and such but rather I mean to place them as a guide.
If you don't give them authority, then we cannot call them leaders at all. If you give them authority, they are not simple guides anymore since they will have the power, implicit or explicit, direct or indirect, to decide on matters of what is 'canonicaly' correct for the community or for a subset of players. For example, someone who 'canonicaly' (as decided by the RPC) is the highest officer of the Immoral Flames below Rhaubaun: he has power over everyone inferior in ranks to him. The only way for characters to ignore his orders in-character is to imply that someone who is 'higher' than him ordered him otherwise. Except the only one higher than him is an NPC who cannot be spoken to without trampling on everyone else's toes.
This positions of power only work well in guilds/free companies/linkshells, because people implicitly place theirselves under the leadership by joining.
It can also work in community driven events when the position of leadership is temporal, a consequence of the event and when obedience is optional.
None of that is true if you appoint players or characters as the higher-ups of canonical organizations.
