I think I'd be mostly happy with dungeons if they got rid of the trash entirely. 95% of trash pulls provide the exact same experience, so after this many expansions it just fees like pointless filler to pad out the experience. If there's a trash pull that isn't providing me with a unique challenge, it's wasting my time.

Which is a shame, because dungeon bosses can be so fun! I just don't want to wade through pointless trash to get to them. So I don't.
