Epeiros will be more likely to take Pella as AI in 0.81. It's happening more often. The problem is that in 272 they were on something of an upswing - if they hadn't sent a large army with all their best generals to the Peloponnese to be totally ruined during that very year. They might be a little too strong in 0.81, but if we see that is the case on AI progression screenshots (posted by fans) then we will probably reduce the garrison in Taras (and fans can do it themselves in descr_strat.txt if they like by commenting out one or two units). But lets see how it goes first.
