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

I would personally welcome it simply because of SE's current "official" stance on parsers. People don't want metrics and numbers and yadda yadda, put a mechanic that in alexander normal emphasizes that you need to at least know the dps rotation for your class. Then followup in savage with a serious check, any minor screwup leads to failure kinda thing.

There was. It was called Titan HM. People could barely DPS the heart in Darklight and AF2 (Hell, they barely did it even with a full stack of echo), how do we expect these same people to defeat a mechanic like that in 3.0?

All that will happen is they will complain and moan and it will get nerfed. Just like everything else in this game after the first week or two. Instead of meeting the problem head on, we apply bandaids that doesn't fix the overall problem.
