A pointless notion much like the guy who was talking about having boss dialogue and things like that. The majority of people just don't really care they run things because they have to not because they want to and they want to get it done as quick as possible. Being used to which trash waves to go through and what they are makes for quicker runs. No matter where trash spawns it's still going to be boring that's just the nature of trash which exists to slow you down and make a dungeon last longer. The only true way to enjoy a new experience is when new content is released.
