As for whether you find the metal processing or frost cave exploration more satisfying activity, that's a matter of opinion. I really appreciated the break in monotony mining for iron, iron and... some more iron, but I must say I didn't enjoy the material drain of upgrading the Fenris set either, especially since I had already explored the nearby larger mountain regions on my world before the update which introduced frost caves.

Fenris set remains viable even in mistlands, thanks to its mobility boost. Wolf armor not so much. Equipping root harnesk, light armor from the previous biome swamp, is probably a better bet in mistlands and plains than the wolf coat.

I replied to this before but I guess it didn't post.

You have a great point about the resistance bonuses on light armor. On my way to Fenris I cobbled together pieces that brought me 10-15 points higher than my root armor set, but suddenly I started getting chunked by Deathsquitos where they were a non-issue with Root. From that angle, I can definitely appreciate Root / Fenris requiring more of a grind than heavy armor.
