Yeah I agree, I haven't done m+ at all this expansion despite pushing +23s last expansion. There's just no point now though, you don't get gear from them, so there's virtually no reason to waste your time.
Getting a WF/TF piece was actually pretty fun and exciting when you finally got something you or your group wanted. Now though you zone into the dungeon knowing damn well there is a 0% chance anyone will get anything of value. Makes it feel like it's completely pointless to bother.
