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

Dude World firsts are because they are at the bare minimum gear requirements that dps matters. After that its way easier to hit enrages/dps checks.

But again to my point, anyone in a World First raid group, isn't going to lie about their dps numbers to their group, if they could see their own dps. So again seeing only your own dps would still work.

DPS never stops mattering, DF t13 and get 4 DPS all doing sub 300 and tell me that you can clear it, identifying problems and removing them (or even fixing them) is a key part of building a strong team that can clear content.
