Problem with Morph mod

[Pansesus]

Many items in 1.10 bestow character specific abilities of shapeshifting. I am wondering how much original stats or animations would the morphed charcters keep. In Necro-Set case, all the animations has been set to Vampire1, but when a none-druid class is morphed into werebear, he / she seems to remain his / her own attack animation. I am confused of this.

Cheers
