I think you're out of luck. Progression past i90, as far as I know, there's only:

-Levi/moogle ex
-SCOB
-Relic grind
-Weekly sold cap

1st option is locked out if you cant beat past titan ex. 2nd option is likely also locked if you're not past titan ex. 3rd option often gets called 'for casuals' but I disagree since it's a hardcore grind. The last option is something you do regardless of the above 3. From my point of view, the casuals gets shafted and has to wait for scraps or wait 6 months for new CT and overall gets a boring mmog. I see lots of players that has access to everything dismiss it and have the 'casuals deserve nothing' attitude and I strongly disagree. The content structure in this game is all messed up and timed poorly imo.

I'm not calling you a casual or anything but right now you have the gameplay options of a casual. Freaking nothing.
