Content geared towards FCs

[Vidu]

"Why is there gear gated behind Savage/Treasure maps/Ex Trials/Crafting/Gathering/"insert story locked behind an job or rolequest??? I should not be forced to xyz!".....

For me there is a big difference between playable content and the rewards that said content offers - all of those contents can be accessed by anyone who wants to do them and its only up the player to get there.
Different story for content that would be locked behind FCs - where you'd be way more dependant on other people. On the one hand having enough people online at any given time to do the content and on the other hand not having so many people online that you dont get to do the content because you get excluded.

I'd like to offer two scenarios here, assuming that when we're talking about "content" we mean something along the lines of a dungeon - in the broadest sense, mainly: battle-content that people play together in a cooperative fashion at the same time:
(A) We get new [content] for up to 4/8/24/72 people. You can invite anyone to join you for this content, including FC-members and friends from other FCs and worlds. If not enough of your FC-members (and friends) are online, you can use PF to recruit strangers or try your luck with DF. If you - and some FC-members/friends - want to play this content, you can do so at any given time (more or less).
(B) We get new [content] for up to $/8/24/72 people. You can only invite FC-members to join you for this content. Any friends from other FCs or worlds are out*. If not enough of your FC-members are online to attempt this content with any promise of sucess (e.g. you dont really need to attempt treasure maps with less than 3 people - while possible, its not fun. At least not in my humble opinion). If to many of your FC-members are online, some might be left out. If you want to play this content, you depend on your FC-members being active at the same time as you while not having other ingame plans.

Why would B be better than A? What would the benefit be? Certainly not making FCs more social - maybe I'm to negative but I can already picture dramas like this:
"Hey, I want to do [content] on monday, tuesday and friday! Let me join your FC!"
"Cool, we do [content] on monday, tuesday, thursday and saturday and we need more people!"
...
"You didnt do [content] for the last two mondays! I'm leaving!" or "I wasnt allowed to join for [content] for the last two weeks! I'm leaving!"
or, on the FC-side: "You didnt show up for [content] for the last two weeks, you're out!"

*funny enough: they werent even that bold - or brutal - for Diadem back then...
