Agreed.
The devs looked to have big plans for the game and seemed excited and optimistic in the beginning.
Most likely, the “higher ups” decided to keep cutting corners (“more profits in the upcoming quarter at ANY cost!!! 
”) and the devs were left with too little time and money to complete their vision.
Just look at the inclusion of the new models, for example.
In the beginning, we got so many unique ones, even for units that were just barely seen in the campaigns (Gazlowe, Snarlmane, Nazgrel, the various Paladins etc.).
As they went down the list, though, it looks like they ran out of steam, and the unique models stopped coming (as of right now, Baine Bloodhoof is still a basic spirit walker unit in the Rexxar campaign!).
On top of that, a bunch of animations are missing— many are simply copy-pasted to compensate for this (see this thread).
Hopefully, the dev team will at least get some funding they can use to patch the game throughout the year.
Even with the cut content, there’s still lots of potential since the original game is so damn good.
In summary, this is most likely the fault of K***** and his ilk.
I highly doubt that the devs deserve most of this heat.
