Forcing NA Duty Finder to be better, we need a grading system.

I think instead something should be offered that teaches players. Teach them why they are "bad" and how to fix it. Either way no matter what the devs put in if people get discouraged they will quit so I don't ever see them putting in something like that.

Only so much of that feels appropriate for an MMO. It'd be kind of awkward if you failed at, say, Titan, and some Protip came up like "Trying avoiding those Landslides, they'll knock you off"! Too hand-holdy.

Guildhests essentially do this though, but bad players don't actually apply what you're supposed to learn in those to other instances.
