There was a thread going on in another forum about whether Seven Star Mantis had the Drunken sets or not.
Most 7* family lineages do not have these sets. The reason being they were introduced and passed on by Master WHF.
Regarding Zhai Yao there have always been six sets in the 7* side. From the LGY side, Mei Hua Lu, MH Quan and MH Shou have never been considered part of the Zhai Yao sets. Too much over analyzing and not enough training!
Hope it helps.
