Agreed on the wars, you never have the time to take care of anything else cause your faction is hopeless without you taking the reins by defending AND attacking.
I agree about the voting system as well, although more than for the fiefs which are useless anyway (they hardly make you any money, most of it comes from the loot obtained during wars) I think the biggest issue is having no way of influencing the votes / AI lord votes making no sense at all most of the times for both policies and war declarations.
We should be able to order other lords around by spending influence (or what's the point of being king) to make wars less frustrating.
Fiefs need a rework, as they are I can't even understand what's the point of having any, in the end game I don't even have to recruit anymore since I have an infinite amount of prisoners that I keep converting to top up my party numbers anyway.
