Apart from the first 4, I disagree with the list. Bishui should be in the top 5. The 5 and 6 should be lower, and 7, 8, and 13 should be higher. They are more aggressive and powerful than the 5 and 6. However, each of them is different and requires different strategies and tactics to beat. I agree that, if you know them for each and every boss, it can be easier even for Erlang and the Great Sage.
