I hope Aatrox's animations are a WIP...
Aatrox's dance on the PBE is the exact same dance animation from his previous model - and it looks weird and out of place on the new model. On his old model, it works because the sword is segmented and collapsible, but with his new model, the sword is a solid weapon, and when it's "compressing" like the old sword did in his dance, it comes across as some 1940s cartoon animation where everything in the world is alive, happy, and bobbing with the music. Please tell me this is filler until a new animation can be made, because this is just not up to snuff for the new model.
