The looming excitement that might be TW warhammer III

O, it's absolutly not surprising. Honestly, TWW III is about as good as you can expect given how diverse the races are.
Plus, the mismatched mechanics between tabletop & TW naturally creates some problems as well (max 20 units, v.s. max 2000 points results in very different armies... expendable units don't work very intuitivly in TWW with persistant armies that build experience but work fine on the tabletop, etc.)

Honestly, the only thing that they've really done badly is how units unlock. Armies end up very unbalanced as you can rush certain elite units while the rest of your army remains underdeveloped (e.g. rushing for heroes, but neglecting your regular troops, or rushing elite infantry but ignoring ranged & cavalry etc.). The process of unlocking new units should've been far smoother. Though again, this has been an issue since like Rome II.

 

I spare them no excuses. Mark of Chaos could have heroes attached and detached from a regiment. For TWW there is only laziness. If the mods ain't doing it, they aren't bothering.
