You said it yourself, “the work that goes into things”
THERE OBVIOUSLY WAS A LACK OF WORK THAT WENT INTO THINGS.
The unit models, animation, SpellFX and stuff all went to a chinese 3rd party company.

Menu lag
Crashes
Desyncs
Bricking the old game
Bugs Bugs Bugs
Problems from the old game
On top of lacking textures.
