KH and Macedon often get in a stalemate with each other, swapping Athens back and forth. Epiros takes Dalmatia but not much after that. Aedui and Arveni also stalemate each other quite often.

So don't expect every faction to expand quickly. Some won't expand at all.
and yet, weirdly, in this sauromatae campaign dacia are MASSIVE and have taken kallatis and ak-ink (sp?) already....shocker!
