Are Roman AI a bit strange at 0.8?

[MaximianusBR]

I am plaiyng a campaing with Kart-Hadast at VH/H for 60 years and the roman AI looks kind of strange to me...They just taked iuvavoeta(sp?) and reunited all 2/3 of their armies there imobile...changed their capital to Arriminum and didn't give too much attention to south italy...
after a war against me they didn't gave attention to my armies and continued concentrating armies at the alps...i almost tooked all italy but decided to return the lands to them plus Alalia and give them 60000 Mnai in exchange for ceasefire, alliance and military acess(a litle gift for them to recover their power)...so after the war they get with all italy less:Capua, Taras et Rhegion...Rhegion stayed with me and Taras et Capua I gave to Epeiros to criate a buffer...
After 20 years a most strange thing happen...Epeiros attacked Rome and conquered it's lands all the way to Arretium...rome have some 3 and a half stacks starring at the alps that cold easily retake rome and the other lost regions and even conquer all the epirian lands at italy, but they just ignore it and keep on vacation at alps while their homeland are conquered...

I think it's a strange behavior from the roman AI...some thoughts about it?anyone had the same experience at their campaings?

BTW, this game rocks!!!
A lot better than Medieval 2!!!
