how much stamina do you have? asking so i can get a roundabout guess for how far you are through the story dungeons.
its another point where opinions vary, but IMO its not worth running dailies until you're pretty much done with all the story dungeons. with an exception for Sunday if your A Team isn't 80 yet, and maybe Tuesday since Black and Power orbs are in pretty high demand early on. otherwise, seems to me that running story dungeons is the best way to use up stamina.
and i'm glad you're enjoying your new toys
told you it would feel like a whole new game after you finally got to dump all your mythril!
