There are a lot of things in this game that were just wasted opportunities or just outright ignored.
1) Influence. I don't like how it's treated like a currency of sorts. It's okay, but it's not real immersive. What it should be is that if you wanted to influence the vote, you should be able to go up to individual nobles and convince them to vote a certain way just as you do to convince them to defect or join another kingdom. This is also why it's so blatantly easy to get fiefs in the game. That would be more fun, but it would only work if we had the next thing.
2) Feasts. This is why the original game worked well with the old influence, albeit crude, influence system. Because you could get nobles in one place, improve your relation which wouldn't change things immediately, but overtime was rather rewarding. And with so much of emphasis on building your own kingdom, it's a wonder why this mechanic was taken out.
3) The main quest. Of all the wasted opportunities, this is the biggest one. If I were doing this quest, I would forget the whole "find 10 lords" crap. Finding anyone in this game isn't a task; it's a trial by fire and now we have to go find 10 of them. What's wrong with finding one person from each kingdom, getting their take? That's it. Because usually if I find the king and then one his nobles, they tell the same story from the exact same perspective. That's redundant! Other than maybe a back story, it doesn't tell me anything about them personally either. Nor does it really tell you about your clan, your parents, or something to make this personal.
Secondly, this quest is just a big time clock. Now, I understand that it needs to be that way for the death mechanic. I get it! But that's all the value the quest adds. It's not like there's any twists and turns to make you go "Whoa! No way!" Like for example if you had your brother (if he's alive) join the opposite side that you do! So, then you have to have a throw down with him and then make a difficult decision as far as his fate. But literally nothing really happens.
If I had any coding skill, this is where I would be putting my first mod. I would be seriously revamping this quest.
