Ignoring the bot issue or overcrowding issue a second, I think it is safe to say that the majority of our dungeons are just lazily designed. They are almost always in a circle that has a one-way door to ensure that there is one way traffic. The boss and soul shard sit somewhere near the end of the circle, and then you take the one-way door back to the entrance.
There is nothing about this design that is interesting or feeling like an Elder Scrolls game. The ES games had varied designs with hidden traps, secret areas, multi-levels, etc.
These need to be changed and dungeons in future updates should not be allowed to look like this!
