The flaming maces are apparently not on fire in Records mode, which is a rather strange choice of a bridge too far, but sure.
Impact damage is out of control for the war beasts, so we're probably going to mod that. Elephants are still pretty vulnerable to ranged units, so they do have a counter. Will have to test how powerful tigers are in practice.
Honestly, with the exception of the tigers, I'm not that upset with the roster. It's probably playing up the tribal aspect too much, but it's at least forcing a different style of battle gameplay, which has been a problem for the game for a while. It's really just the tigers that bother me. They're essentially stronger war dogs, they're apparently limited, and they don't change the game 'that' much, but my mind just recoils upon seeing them.
We got confirmation that Nanman can reform themselves to use Han units, and that Han and Nanman generals can be captured and employed by the other side, which lets each side field the others' units. That mostly just makes the Yellow Turbans the weird outlier who can't do that.
