Leveling Rio is over. Now what?

Looks like I haven't gotten a goal to motivate me to play GE... Let me list down a possible set of goals I can accomplish:

• Level up my characters using firearms so I can AFK level in peace.
• Level up my construction workers for more power leveling options.
• Level up my main characters to progress forward.
• Level up the other characters to 72 at the Rion Dungeon Hollow.

I sure pretty need some advice at this point. I would to have a direction right now. What do you guys think?

What I've accomplished so far:

• Having a Veteran Catherine.
• Reaching Veteran for the main team.
• Having Rio reaching Veteran for the in-game event.

That totals it to five Veteran Characters. Well, I hope I would get some feedback from you guys. Catch y'all later! :D
