Noggenfogger is still bugged for druids. This was a very significant item that druids used for PvP back in vanilla. It is even stated on Blizzards known list of bugs, so they are well aware of it.
Please look to fix this before BGs are released.
For anyone who is unaware. The Skeleton form appearance is supposed to remain visible, even while in cat and bear form. Currently, you retain the buff, but the cat form/bear form model overwrites the Skeleton form. This is not how it was in vanilla.
Edit, since people seem to think its not a bug. Or that it was never this way in vanilla. WoW Classic 1.13.2 Known Issues List - 8/27/2019
Also, those who want it to stay “fixed” well, that’s silly logic considering they’ve relatively kept to nochanges. Why change druids?
UPDATE: They fixed this. Skeleton form now is retained while in Cat/Bear form. Thanks Bliz!! Sorry to all those people who clamored we were wrong lo.
