Would you like an in-game parser?

I'm not going to hurt 7 others progression to make 1 person who doesnt care enough to learn happy

Problem is, in the grand scale, it's not your call. Each person has its standards, and they'll all honestly feel that it's not that difficult to achieve. But this is so subjective that you'll have a very hard time to agree with everyone. Let's say you ask for 1000 DPS for your team, someone less tolerant might ask for 1200 or 1500...
That's why the standards should be decided and enforced by the game. It's the only one against who you can't defend yourself by the dreaded "I play how I want".
