I think cavalry, and I'm very sure about that, is still much too strong, and champs in comparison too weak.
I would suggest that cav cost at least 125 Food 75 wood and 2 Pop. I would them also make them a little bit slower and/or give them less HP.
Hunting gather rate from 5 to 2.5 (like borg- advises). For that reason cost of goat or sheep from 50 to 40.
Champ Sword and Champ Spear: more Armor and 50 Food less costs.
Reduce range of Cav Archer and Cav Skrim: makes historically more sense and makes Spam and hit and run more difficult.
Make tower a tiny bit stronger.
Slinger Range from 42 to 32 and Javelin Inf attack from 16 to 13
