Cabal promotions, from my experience, are dependent on many, many things. They range from a character's RP, PK, and their overall ability to handle that position. Not only that, but the IMMs consider the player behind the character as well. Standards change depending on who the player is. IMMs will see that a particular player has excelled or struggled in the past and expectations will rise or fall accordingly.
I can see merit in both sides of this argument and I've argued in favor of both of them throughout my time here. Its a difficult thing to impose a time limit when you certain players can reach those times in a week and another player won't be able to power game through those standards. The biggest thing, in my opinion, is directly comparing yourself to another player. I've seen many, many times where another player has rolled a character, gotten 50, into a cabal, and gone through Inductee to Elder and even Leader, before I am able to make a single promotion. This is EXTREMELY frustrating as you're left wondering what the hell is going on? Asking for a promotion is basically a death sentence and you're sure as HELL not going to get it if you ask for it.
Warmaster, for example, promotes very, very quickly. Watcher, on the other hand, is probably the most "ignored" of all the cabals in the game. And all the others fall in between depending on the IMM's mood or play times. What would work?
Some brainstorming:
If a specific cabal is under three(two?) members then automatic induction is in effect until that number is reached. Characters will be moved from Trusted in Clan to Cabal Inductee using an approved criteria set in place by the IMMs.
Elders are capable of inducting characters into the cabal if the cabal IMM or delegated IMM in charge bestows that power TO the Elder. If your cabal does not have an Immortal currently, then you can seek approval via application.
Leaders are capable of inducting characters into the cabal and promoting characters up to Trusted. Leaders may submit a vote of promotion or a note to the Immortals requesting a promotion of a character in their ranks to the position of Elder. At any time the Cabal IMM can deny, demote, or remove any member, or potential member, as they are the overall authority of that cabal. If the leader is found abusing this power or is suspected of OOC behavior, then they will be demoted to Trusted, or worse, depending on the severity of their actions.
Leaders must have a valid reason for every action they do and will be expected to justifiably answer for them. IE: Why did you promote an inductee of two days to Trusted already?
Of course, the Elders and Leaders will have the same power when demoting a person. If they feel you are to be demoted then they will have the authority equal to their authority to promote with the exception that a demotion or removal, in the case of a Leader, will require a note to the cabal IMM detailing why this happened. IE: Insubordination, attempted coup, breaking Knight Commandments, what have you. Elders/Leaders will need a GOOD reason to demote and an even better reason to remove a character as this can be a very steep punishment.
I am 100% in favor of giving Leaders MORE control of their cabals. Leader is terribly difficult to get and it is basically the pinnacle of our character's progression. Yes, RP can always progress and you can always achieve more through it, but leader is often seen as a crowning achievement to a character's life. It should not just be a nifty cabal power.
