So your seductress can't just instantly collect all the best men in range.
Bah, a seductress can just seduce them to her court. But yeah, it's probably to prevent poaching good characters. I still think opinion influence is capped too low though.
Anyway, back to griping. I absolutely hate how they removed ships from the game entirely. Yes, the way they worked in CK2 was tedious, but even that was better than this. The way AI uses this ability to turn into boats is just jaw-dropping stupid, and I only started playing this game. I declare war, they turn into boats and sail for my capitol. I smash them, they retreat into sea, turn into boats and sail for my capitol. A completely land-locked eastern european country is easily sending their troops over to Ireland. Overseas enclaves everywhere, because sea as an obstacle is meaningless now, as are straits and other choke points since all can be bypassed by just walking around them over water. Seriously, fuck this shit.
