Casa Muertos Quest, What does it mean?

[Basil Dreadflint]

Here's a situation and some questions regarding the Casa Muertos Quest.

Disney has posted that this quest is only going to be available on Test for 3 days. The notes say that it is going to be available on Open starting September 4 and running for about 3 weeks.

Since WHEN does Disney release a TEMPORARY quest, and make it level dependent???
We have proven that the final section is only available to level 20 and above. Disney has never done that before. All the special quests in the past have been available to everyone! Especially if they can only be assigned for a limited number of days.

I mentioned before, I think this quest may be a lead in to the second story chapter. (Not immediately open it, but maybe have something to do with it.) The Casa Muertos Guild is working for Jolly Roger. By helping them, we the pirates are working for him, too. I believe that some of the things we are supposed to get for them are things that Jolly Roger is seeking to help him gain strength in the Caribbean.

So, here's my quandry.
Should we even DO this quest? Does it mean anything OTHER THAN gold and rep? By doing it, are we falling into a trap because we didn't listen to the Game Master's warnings about not helping JR and the EITC?
By doing it, is it going to open up something NEW (not immediately, but sometime down the road) for those who complete it?
What happens to those who DON'T do the quest, or CAN'T do it because they are too low level?

IF it is nothing more than rep and gold, since when does Disney put out a quest that the littlest pirates can't do? Is this a sign that they are finally starting to realize that they should cater to the high level, long time players? Like raising the caps does?

Lastly, Other quests, such as the Father's Day/ Mother's day quests, if you took them on and didn't finish them in the limited amount of time, they stayed on your journal quest list, and you could finish them aytime you choose. Will this be the same way? If I take them on, but don't finish them, will the Casa Muertos Guildmembers still be there for me, or will they go away?

I think that Disney has a special purpose for those 5 guys. I don't think that they will be hanging there by the dingy's with absolutely no purpose in being there once the quest is done. Either they have some other future in the game, or else they will just disappear.

I plan to finish the quest on one of my test pirates, but not finish on my second pirate. That way I will know what happens in both situations. If they just disappear, no big deal on the lost rep and gold on the second pirate.

I pose all this just to get everyone's reaction.
