Auto herald 3.4 rip?!

I have no idea why that is so but in delve league automaton herald, the ice one especially looks awful. Seems like it lost half of its explosion animation and/or just became mostly dark instead of fancy blue since 3.3.
There are some vids with this mtx in 3.3 and in 3.4 accordingly:

3.4 https://www.youtube.com/watch?v=NGFATFnlxXs

MTX are made to make the game more enjoyable in my opinion and i honestly dont get why something looking so great got killed after couple months from release.
Just hoping im not the only one seeing this, ggg fix pls.

P.S. Ash herald received the same "nerf" as HoI.
