Snowcloak, the one dungeon where you fight Midgardsormr, Suisui. I don't mind Suisui in leveling, but damn, getting either of those two 50 dungeons if im 60 S U C K S, so much of your kit gets removed for the vast majority of jobs and it makes it dull.

Also I always get ARR raids, I spent a month leveling both DRG and BLM and got n o t h i n g but those raids. Same story of the ARR dungeons, half your kit is gone.
