I can not agree that Shadow Weaver, Evil-Lyn's equivalent or superior is 2nd Tier. She was in nearly as many episodes of She-ra as Hordak himself.
If the line lasted another year or two, it's possible they would have made Weaver, Scorpia, Sea Hawk, Imp, Madame Razz & Broom back then. But everyone on the Filmation Banner that where in one or two episodes really do not deserve being made into a toy, I would not be excited for a Chef Allen figure. Then there are the one hit wonders that made such a impact, that I would love to have as a figure. Icer, Evil Seed, Hunga The Harpee etc. But that is just a handful, more than likley not worth the cost of Filmation rights, even if it does include other properties they may or may not make money on.
