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

Maybe someone has already said this, but what if they only showed you your own dps number.
That way no one knows how much dps anyone else did.
Individuals could use the metric to adjust their strategy on fights to achieve better results.

This would keep players from being harassed about low dps, but still give the community and individuals valuable information.

Information is only valuable if it can be compared, knowing only your own DPS does nothing for you.
Instead of bemoaning parsing because some people might get harassed, welcome it so they can improve.
