Zoe's mouth is animated.

Rework Poppy’s is animated...not sure if that counts.

Yea, that was the one thing about . Super fluid animations, but try to avoid looking at her face when she talks, just head nodding.

All the updated Yordles have fully animated faces, since that's the only expressive part of their body, with the rest being so small.

Poppy has an animated face, Kled probably does (but I don't play him enough so I don't know), and Tristana to a lesser extent (though DT Trist has more facial animation).
