Think about Sea Raiders like Viking Raiders (Like they're based on). A viking raid party wouldn't be an organized party that was drilled in tactics like a professional army would. They know how to use their shields and weapons since from their point of view, that's all their need to know to slaughter peasants and raid villages.
If we are going for the historical analogy, there would be no Viking raider that did not know how to fight a mustered Fyrd or local village militia in a shield wall. They could use formations such as the swine array, especially as
we even have the Skein formation in the game. Against peasants and monks? Sure. An organized mercenary company? You can be damn sure they are employing tactics.
Bannerlord improved the AI of enemy lords and sieges (Navmeshes are not the same as AI. The navmeshes in sieges are wonky and that's why the AI is wonky). "Improving" the AI of bandits are not what I think they should focus on, at least not at the current moment.
I disagree. They are so ubiquitous as to be a vital part of the early game. There should never be a free source of XP and loot as they are at the moment. This is simply poor design and frankly lazy. Risk/reward might be gamey and a bit artificial, but it is by far the best option for increasing tension and challenge in a game. So far Bannerlord lacks both of those.
On a personal note, I much prefer to play the game as an unaligned mercenary commander than a wannabe Lord or vassal, but that's just me.
--------------------------------
II'll admit I've found the most recent updates quite fun, but this element of the game needs the bolts tightening up. I propose:
-Reduce the number of outlaw parties on the map by as much as 50%. They are
swarming most of the time and some come in stupidly small numbers.
-Remove the exact party numbers unless you have a high Scouting skill e.g descriptives of the approx number to increase tension and make it more of a considered decision.
-Let the bandit party leader level up, maybe even so they can develop unique names. Let them use basic formations. Make them more of a threat.
-Have negatives to attacking outlaw parties. Repeated one sided slaughters should
reduce moral, not increase it.
-Have more reasons for outlaw parties to come after you rather than 90% of the time running away. Let small parties band together as one group and, if you are carrying lots of goods or have lots of money, actually do some banditry by coming after you. Doesn't that make sense?
This is just for starters. I'm sure there are other ways to improve them.
