In battleground, the black captain's score is far outweighed by his difficulty. He's a lot harder to kill then 7 soldiers or 2.5 assassins for example.
It would be awesome if it said exactly how quick the attack speeds are so I could calculate which one is better. Protip - "Fast" isn't a measurement. Be nice if I knew what the skills would upgrade to. And it would be great if my guy did what I told him to do more than half the time.
Crappy AI healing ie all your priests heal when only one needs to make not losing a unit impossible. Also the fact that infantry move quicker than priests is just stupid.
