The new AI is overall an improvement in my opinion, now that low tiers don't block as effectively as previous 1.2 patches, and the AI focusing less on the player when there are other units nearby is also great, but there are some important issues that should be looked at:
- As everyone and their mother has said, being able to block against a mounted attack with full speed with a spear, swinging polearm or 2 handed weapon with a flimsy 1 handed weapon is massively immersion breaking. A form of dealing damage through blocks to enemies blocking with 1 handed weapons is crucial.
- Shielded infantry, regardless of their tier, blocks too much, which is especially noticeable in tournaments and sieges against militia who take too long to take out if they face you. Decrease the low tier units' shield durability so that at skill level 150-200 without any with shield damage perks, they get destroyed in about 4 hits from a 1 handed (non axe or falx) weapon or spear, around 3 hits from a non-axe (or falx) 2 handed weapon, 1 handed axe and swinging polearms, roughly 2 hits from a 2 handed axe/falx, and in 2 hits from a 1 handed axe with shield damage perks, 1 hit from all 2 handed weapons with all shield damage perks and have the 2H axe and falx deal extra damage to the enemy unit if they overkill the shield.
- 2 handed weapon & swinging polearms duels in tournaments feel awesome against high tier enemies, but low tier enemies seem like they choose a block direction randomly and get taken out. The problem isn't that they aren't good at choosing the appropriate block direction, but rather that they don't adapt to change their wrong block direction fast enough even in cases where the player holds the attack button for 3 seconds.
- Melee Cavalry still needs a bit of tweaking to their accuracy against foot troops, in addition to the fix for the 1st issue mentioned.
- Pikemen are generally ****, and honestly all spear & pike units when fighting against other infantry are also ****. The latter is more of a damage formula/balance issue, while the issue with pikemen is both related to their damage output and the AI.
- The AI troops (and possibly the player troops as well) seem to largely ignore nearby enemy units inside their formation if they're in movement. They should be more reactive when for example a few horsemen are attacking their formation in movement.
