Please implement something to teach players how to play

[DPZ2]

Just introduce the rating system at the end of the dungeons that will vary between 1 and 5 stars and will take into account an amalgamation of things: DPS, hps, overhealing, apm etc.
A very subtle way to indicate player's performance without introducing DPS meter

"Screenshots, or you're lying." [Typical response to PF request that says 'Only 4-5 stars need apply' ... oh, wait, Yoshi P has already said that's what they want to avoid.]

Still beats inflated gear requirements or near-immediate disbands to make up for or reroll on the "1-star" players in your example there.

We've gone from "Do you have this thing (ilvl, prior achievements) that might point out likely performance in the content you've signed up for" to "Did you do quite well in the version of this fight one difficulty lower?"

The horror. Whatever are the players who made up for meritocratic disadvantages with gear or enough re-parties alone to do to keep their relative prestige? Players with specific skill and preparation might be able to skip that BS now. Terrible. Just terrible.
