1.1 seems to have done these things so far -

Nerfed the Sweboz
Severely nerfed Baktria
Slightly nerfed the Ptolemaioi
Stopped Makedonia northern expansion
Sauromatae & Saka expand rapidly early on
Pahlava carves out a consistent "Caspian Empire" and much better than before
Improved Lusotana & Getai expansion, fewer to no factions failing to expand - even Casse gets something.
Improved Romani so they don't get stuck in Italia anymore, instead they rush to Massalia and southwestern Gaul.
Improved Aedui, who always take a 2-1 province lead over the Arverni, with rare exceptions (like AS vs. Ptolemy)
Pontos often is able to carve out a nice empire

Things that need improvement

Hayasadan still always takes to the steppes
Saka/Sauromatae stall after rapid early expansion
Baktria is now very weak compared to before.
Arverni are utterly destroyed by Aedui, the fight used to go on for ages
Casse & Saba still weak, though I suppose this is historical
Carthage never really does anything until 220 BCE
