DPS display could easily be solved with a system already in game.

I don't see a problem with the way it is now, everyone has them, you can talk about them with friends, but you can't target people in game with the results.

What's the problem?

Wrong. Not everyone has them.

The problem is is that there are some douchebags that will use tools, such as parsers, as a bludgeon instrument to stroke their e-dick.
