Despite all the focus on the negatives here, it sounds like there was a lot of positives too, and they thought it was excellent overall. There's some good info in there and my thanks to those who translated.
Sounds normal for Easy difficulty. Given it's a tutorial Prologue campaign, the AI may have even more restrictions to army size and recruitment.
Hope this isn't really the case. Line of sight is a great idea, but only if the AI can't psychically know where your men are. From what I recall though, sound also plays its part, so the AI would 'spot' marching troops even if they're out of visual sight.
Sounds like a bug maybe.
Bug?
Might be a bug, but it all depends on the context. Placing archers on walls may seem like the 'appropriate' thing to do, but that isn't always the case. I know I don't always do it in sieges. It depends on what troops I have, what type of troops the enemy has, the state of the fortifications etc.
Agreed. S2 wasn't perfect, but was a big step up. Hopefully R2 will be as good, if not a little better. Obviously the AI has new systems to deal with this time around (LOS & navy landings in battle maps) so it's hard to say how well it will cope with them until we get our hands on it. But there will always be AI bugs here and there. Always. If you expect a perfect game AI you may want to adjust your expectation because such a thing will never happen. We just have to hope they are fairly rare, as they were in S2. INB4 'fanboy'. Nope. I'm just being realistic. If these 'bugs' occur in every other battle I'll be as displeased as the rest of you. But if they only crop up rarely, then I won't really mind. Although I'm sure some people might hit a single AI bug in 10 hours of play, rush to TWC and proclaim it '0/10 AI is

!'
Well, difficulty doesn't make the AI 'smarter' as such, but it can influence its behavior in the same way that Darthmod 'improves' the AI. The bonuses it receives on higher settings can make it far more aggressive, as it has the forces and funds to act, and react a lot faster to player expansion. On say, Easy, it's a lot more passive because it simply can't field the same level of stacks as on Legendary.
I have a feeling we'll be seeing a video of the prologue campaign soon (at least I hope we will) so we'll get to see it in action for ourselves. I'm still cautiously optimistic though. It looks like the campaign side has gotten the overhaul I hoped for and all the new features sound great.
