I noticed that Baihu had an unused animation called precision strike. This must have been the special attack originally announced, powerful strikes that send enemies flying. It seems to have been replaced with maul, which is now a wider AoE knocked backed with a single unit stun and high damage.
Personally, I prefer the maul ability. It is a little more unique. Knock backs are a bit generic and have been overused a bit. What about you?
Y is Baihu have red enemy color?
I set the colour to red in the editor 
Baihu does look like a rushed unit. Its price is bizzarely high for a heroic age unit but lacking minor god improvement tech, it often leaps into terrain and got stuck. Its built-in combo often targets the weak unit and overkill animation also stuck it and wasting dps. Taotie however is a very well-rounded unit with two(three if you pick Zhurong)improvement teches.
