I had the same thoughts about plains first. I think everyone did - that "bzzz" was coming to me in nightmares. When you are just running angrily - you will just die. Again and again. However when you learn the patterns, when you know exactly when to dodge, those MFs stop being a problem.

When it concerns mistlands - the situation is absolutely the same. Anger makes you to copy mistakes. From bugs it is easier to run, attacks of floating thing can be blocked with rocks or buildings, dorfs can't harm you if you just sit somewhere in high ground and shoot them with a crossbow.

Or yea, choose the easy way. Why not.
