2. We can run faster than most.

Not when debuffed by the water. The imbalance, as described by @Aimee, inhibits immersion.

That's why we have other mobs, like Trolls, that can smash through the obstacles even we have to go around. Do you really want greydwarfs to be more difficult to deal with when we have other mobs to fill that niche?

Some of us may care about aesthetics a little more, or perhaps, you know, not want to do teraforming mid-combat.

Only after you look at them the first time. And how does that make a difference. They know where we are just fine (and I would say even more than we know where they are, even with their "big signs").

3. Vis #1, we can kill them over and over using the same technique. They can't learn.

Sure, you have a point here.

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.

As a game developer in passing myself, I like feedback about what is potentially problematic or irritating in my games. Not so that I can drop everything, because reasonable people understand issues aren't usually resolved in a night, but so that when I can get to it, I can make decisions about what should be done to address the matter. This includes whether it is an irritant I feel belongs in the game.

P.s. Also, I totally agree with you, @Cap'n Bells, about the awkward hill attacks.
