Would you like an in-game parser?

Rude, bad, players might ask for your dps, but most players will just say their dps, when they feel they did well and not expect you to say yours.

I don't think so - I wager it'd be a common occurrence in runs that don't go particularly swift or smooth. And I wouldn't stereotype those players as rude or bad either - some genuinely want to help, others just want to kick whoever is making this run go 30 instead of 20 minutes. Some people are bad and seek a scapegoat, others are so used to a higher level of play that they take it for granted. Some people might even just want to stroke their E-Peen. Motivations differ.

I just fully expect people who do not want to disclose their DPS if prompted to be treated as if they were bad players, because people like to go with the logic:"There is no reason to hide something if you aren't doing something bad.".
