Square Enix, please create level 50 guildhests

I know this may seem like an odd request, but guildhests teach you how to play this game as a team. I believe they can be utilized as an effective tool to build teamwork fundamentals between players--be they level 1-40. But that's the problem. It stops at 40. We need a level 50 set of guildhests that we can run with all of our abilities to better prepare for the Binding coils, Titan Hard Mode, or even just helping a fellow FC member improve--even a random player you'd meet. Make the reward for completing them 5 philosophy & mythology tomes, or don't (I think it's a small enough reward for learning to work with others.)

Make the difficulty of them -challenging-. As in, not to the level of Titan HM but surely not easier than ultima weapon. While running Primal battles to build team work is good, it can only prepare you for -that- fight. I believe that a variety of level 50 guildhests that teach you to move out of AOE's, combine skill usage and timing would be a useful tool.

L40+ dungeons SHOULD have been 8 man in the first place. SE failed an important part there. There's too few 8 man dungeons. >.<
