I don't think we really can agree on that, I've seen some very bad players kill final floor Savage fights. The advent of X-World PF has allowed some very poor players to get carried, because most of these fights (even savage) can be done basically 7-man. There's also a depressing level of people who have been sockpuppeted through Ultimate, and some even started buying parses so that the Site that Shall Not be Named has a recorded ranking of their character clearing it, which makes it harder to see if the kill was legitimate (ie, not sockpuppeted).
I see the point you're trying to make, it's in service to my own point though. Progression gear, Square decided, cannot be too difficult to achieve because that causes arguments about non-elite gear having similar stats. It makes people who kill Gordias Savage 4 ask why people who do Diadem get i210, when Diadem doesn't ask for nearly the pound of flesh that Gordias Savage did. Prestige gear bypasses this, because you didn't kill Ultimate for the extra materia slot; you killed it for the title and the weapon glamour. That's the balance I think they're trying to strike with Ishgard--the rewards not being for progression, but rather for prestige.
I don't know what direction can be taken for crafting. I just know that the creation of Ultimate made all of the progression have an end. Savage is now a means to an end, and that end is the hardest fight series in the game. Having that direction made Savage bearable for me, because even in its dull ease, I knew I was working toward a greater goal, and a greater challenge.
