I liked Vase Off. It was easy enough to do, you could clear it fairly quick, and(this is important to me for some reason) you could teach it to someone else fairly quickly and easily. But i also like jumping puzzles like the tower climb, and my one try at LoF this morning was fine. Skinchange is the one i think used to spawn too often. The difficulty was typically fine, but any time they spawned a Roe NPC i would turn right around and leave the area. I can only sometimes tell those things apart anyway, and almost every time i tried the determining factor would be the height of the stupid thing. You know, height - something thats really tough to judge without some sort of reliable scale(which we have none of in the saucer).
