We have many advantages over the mobs.

1. We are way smarter than they are.
   
2. We can run faster than most.
   
3. We can jump over obstacles they have to go around
   
4. We can shape the terrain to our liking.
   
5. They have big signs over their heads to tell us where they are.
   
6. They have to telegraph every attack.
   
7. They have to warn us of their presence by making noise.
   
8. Vis #1, we can kill them over and over using the same technique. They can't learn.

So we've discovered a tiny situation in which mobs have the advantage. #1 allows us to do something no mob can do: It allows us to say, "That situation is bad for me. I think I'll avoid that situation."

Of course, it also allows us to harangue the devs to immediately drop everything and fix this terrible mechanic. As a break from complaining about how slow Mistlands is.
