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

Its always amusing to see people downplay the negative behavior that being able to freely harass people with parser numbers brings. Give personal parsers so players in statics can learn and improve, but adding it freely to be spammed in PUG content is just wishing and praying for toxic behavior.

For one, harassing people is already against ToS. Secondly, they are already "spammed" in Pug content. Any PC player that wants to view their own DPS which is a lot already have them, yet the Apocalypse of "toxic behavior" is not upon us.
