Im unsure what is currently wrong with the current rules out of the complaints of AC class which from what i understand (in my limited knowledge of dnd) is that it effects accuracy to much?
The main issue is that it favors certain abilities for the player versus others, limiting player choice. Mainly attacks that are derived from "d20+Proficiency+Modifier versus enemy AC" benefit with a higher success rate and attacks derived from "8+Proficiency+Modifier versus enemy d20+Modifier" (Spell Save DC) don't benefit. There are other factors, but this is big picture.

How does it offer new builds? We currently have less sub-classes than 5e and don't have the ability to multiclass. I'd actually like to see a write up on how the new rules are better. When it's been discussed with written thoughts and opinions, Baldur's Gate 3 appears to have fewer options for builds and tactics. I haven't seen anything to rationalize the opposite.

Having lower AC makes the game much more interesting in the way that it validates tanking oriented build more inline with current industry standards of using a holy trinity (heal, tank, damage) form of game play. This is highly important for validating specific fighter and cleric builds geared toward that feat. If it was easier to hit people these builds, and subsequently heavy/plate armor would be heavily invalidated.
But they didn't change the equation, and not all attacks and spells use the same equation. Someone actually did an in-depth review of the impacts of lowered AC and raised HP and it's mainly to make turns-to-kill more consistent with less variation. Essentially if a player uses an attack from "d20+Proficiency+Modifier versus enemy AC" it will take fewer turns to kill enemies than using "8+Proficiency+Modifier versus enemy d20+Modifier" (Spell Save DC). In the current meta, the player has to take a handicap if the want to use spells based on "8+Proficiency+Modifier versus enemy d20+Modifier" (Spell Save DC). Spells derived from Spell Save DC are there to help combat high AC enemies. Lowering AC takes away their intended use.
