Re: 1.2 Faction observations
Im playing a Very Hard/Very Hard campaign on 1.2 as Venice just now and I will say two things.
I don't know about Milans' aggresiveness but they are still pure arseholes. Also, the HRE broke our alliance and attacked me. Im not saying that's a problem since our relations weren't great but I expect loyalty dammit!
That is all.
Re: 1.2 Faction observations
One thing I'm facing in my spanish campaign, is that factions are very likely to declare war on the pope even if he has not attacked them in any way. First, Milan attacked him in florence, sicily in ajaccio and then the french just declared war without joining the fun. This happened quickly, about 5 turns or so.
Yeah, and Venice are one their way to take over Italy here too...
