Once I hit the ceiling (Lt. 2 & hunting log finished) with the Flames, I saw a new quest pop up from one of them... was to essentially go do Ifrit Hard, which I just finished. BUT there was no completion to it. Asked a friend who tells me I should have been told to go join the other GCs, cap them then come back to the Flames. Not sure I see what that may bring me... as it is I have 32k+ seals and virtually nothing to get with them, so not sure the other 2 GCs will offer me anything better.
