Would you like an in-game parser?

[Reinha]

Admittedly, I want a parser, so that players can see their number and compare it with others - so that they can see how their relative performance is without the need for someone to tell them.

This can be solved with a personal parser too. The developers have already made training dummies for instances with a certain intended entry item level. They have the knowledge what different jobs can do at different item levels. So instead of players having to guess if their team members are a standard worth aiming for (you don't always get paired with your own job, you don't know the item level of others and you don't know if they are craptastic or legendary players), the personal parser can give (A) red-yellow-green colour scales for your dps number, (B) a tickable box in the window that reveals a good dps goal for your current ilevel or (C) a dynamic percentage that compares your dps to the optimal.

I know savage might require you to find the weak link to clear it, but you specifically mentioned dungeons and Midas normal, the places where people go to practice dealing with mechanics and to have a stress-free time. This is how you can offer a tool for improvement with no harassment, no player made standards and no competitive atmosphere.
