RP needs to be removed from keys. Boss one liners and people talking in the background is one thing. But we should not be waiting on people to talk. We should not be waiting in NPCs to open doors. We should not be waiting on boss monologues. There is M0, Heroic, and Normal versions of the dungeons for RP and story.
It drops something other than trinkets for me.
Not only would I remove the squish, but along with that, Iād make the first like 2-3 key levels queueable. Gives folks a chance to get familiar with the mechanics of an M+ without the hassle of finding a group, and the extra key levels back means more folks doing the easier keys. These two things would probably double the amount of players doing M+.
