I'll second the Vampire Queen and Corpse Eater being boosted, as well as making the seniors take longer to die. Also perhaps have Old Age work by the percentage of the 'in his prime' time period, due to the also-aforementioned '51(50)/1001(1000) issue. Fire boosting aging would probably be much less of a problem itself if aging worked reasonably.

Seduction also feels like it doesn't work nearly often enough. I could swear it's literally impossible to seduce an enemy with the Oriad, though I haven't gotten the chance to try with Succubus. Some even consider it a glitch. Perhaps also add a way for such characters to improve their seduction ability.

EDIT: Also, not sure if this applies, but I could swear the AI will always go for you first before fighting other AIs. Doesn't really make sense.
