I know Lady got a series of nerfs before, but she's still horribly overtuned. Queen HC, PP HC, Sindy HC, Halion HC even LoD are done before progressing Lady HC, when she should be easier than Marrowgar, just as it is in 10 man. She is not quite there yet, in my opinion she needs another damage reduction, specially for spirits, and a bit less HP. There's just no room for error with her and at the same time she has so many mechanics that the fight becomes a mess in a blink of an eye.
Anub'arak 25 is another boss avoided by LoD guilds. A ToC boss is harder than ICC's last bosses, how is that even possible?
