I want a damage meter!

Except console players of course.

While the example above is probably a bit too indepth for a built in meter, I wouldn't be opposed to some kind of 'Battle Report' feature, that simply graded your performance at the very end of a duty after commendations had been made.
Something like Speed of Completion, Personal DPS/HPS, Enemies killed, etc. and simply gave you a 5 star rating in each field.
This at the very least would alert those who are playing badly to that fact, and some metric by which to measure improvement.
It would also give incentive to go beyond simply 'clearing the content'. Day 1 savage prog would probably see everyone getting 1/2 stars, but by week 3 when everyone's mastered it, you'll see 4s and maybe 5s.
Could even tie it to a very minor reward, something like +10% gil for each star.

That's not a terrible idea, although I think making the "stars" hidden to everyone but the player they apply to would be the way to go. Keep it for personal reasons, allow it to be enabled and disabled at will and that would be something to look into.

Of course, make it purely personal.
Can't be abused out of people demanding to know what rank you got, which I think sounds pretty weak, but even then, it's vague enough to not be too informative to others.
It'd simply be "I only got 3 stars last time, I should try for 4 stars."

The 'Speed of Completion' would be the party-wide metric to go by.
The 'Personal DPS/HPS' would be your personal metric to measure improvement on.
The 'Enemies killed' would be the dick-waving grade to boast with, that wouldn't overtly shame anyone for poor performance.

Oh it would be abused. Back in the late 2000's WoW had an addon called GearScore, which took your average ilvl and compared it to what was needed to clear something and when you were overgeared status. Orange was "clearable, but needed to work for it" while Green was "overgeared" for the content. You had plenty of people enforcing "green or better" for raids and what not even when they themselves were orange or worse. It was terrible, and directly responsible for a lot of original vanilla WoW players deciding to up and leave (keep in mind these were people who were just peachy keen on pretty much any other mod, including dps and threat meters). Point being, it really ruined the enjoyment of the game because it was such an arbitrary thing.

Translating that to here you'd have people requiring certain star levels/hps/damage total thresholds - proof provided via screenshot - or else no admittance. The same restrictions on ACT usage with others would be enforced of course, but that wouldn't stop the min/maxing munchkins from attempting to do what's in their nature.
