I reluctantly agree with the removal of autoblock in principle. Singleplayer doesn't encourage the player to utilise the one thing that makes this game so unique: the combat.
But therein lies the issue: singleplayer practically forces you to fight absurd numbers of enemies at once in order to progress, and the issue is way worse in bannerlord than in warband. Everyone's campaigns seem to start with hours upon hours of kiting looters on horseback. The game very rarely deviates from this formula outside of the arena, which is optional. An entire game mechanic goes to waste because warband and now bannerlord are designed so that blocking is never worth it.
In a parallel universe version of warband which was more about the player running around as an individual fighting other individuals, autoblock should definitely be removed. But the current game is more like dynasty warriors than anything else, so it really should be in there.
