New units. Their discussion and selection of upgrades.

I don't know, I think the new tier of dancers is much better than the old one. The old ones were completely useless; they had low damage and a useless retaliatory attack, plus their ability was also useless because sending them into a group is complete suicide. But the new tier is very good; thanks to their high speed and corresponding ability, they can control all the critical points on the battlefield, where they need to defend or attack. Overall, it's a very useful unit, especially compared to the old ones.
