Its far from my favorite raid aswell, it was pretty fun to run it the first few times but got boring incredibly quick. Some boss fights were interesting, and I kinda like the concept of raiding my own capital city, but for the rest it felt lackluster. I don't even like the Underhold, most boring place in WoW.
Throne of Thunder is my favorite MoP raid, despite being so lineair. I liked the dark theme, going into underground caverns, and Lei Shen himself was a great fight. The thrash was also done well, great raid.
