I agree with many here that Baldur's Gate 3 should more closely emulate Dungeons & Dragons 5e mechanics. For instance, they could make 'shove' a bonus action and remove the bonus action requirement for 'jump'. However, when it comes to Armor Class (AC), I'd appreciate an aesthetic change. Instead of an attack simply hitting or missing, damage could be mitigated. For example, when playing at the table, if a Paladin in armor is struck, I'd describe it as the hit being deflected, rather than a miss. Conversely, for a monk, I'd say he dodged it.
