Thank you for all your replies, I was just seeing it as "Me VS some NPC" in duels/combat, I didn't think about my NPC troops against the enemy NPC troops(which may actually be a good change), I am just annoyed about how it's too hard for me to hit anything, and nearby impossible to hit it if they have a shield. In the tournaments for example, they just block way too fast after making an attack, and they have this "random blocking to every angle" thing they do, right before you try to attack them, or even if you are just near and focus the camera over someone (not every enemy seems to do that, only the one you have your sight on), I haven't seen if they do the same against every other npc, or just against the player.
Maybe the answer for me would be to "become better at combat", but I don't have the reflexes to do so.
