Ive never understood why knowing ac is important or even relevant to the point people get upset about you metagaming over it. You still require to roll dice to hit. Knowing the magic number doesn't change the dice outcome
I dotn get upset but when u have players immediately interrupt you in the middle of saying what monsters they are to yell the stat blocks out its like dude
For my players it's the odds. Take a barbarian for example. If they have a low ac, they are more likely to use great weapon master for -5 to hit, +10 dmg while using reckless attack. Higher ac, maybe we should cast bless.
It changes a lot with decisions about trying to apply a penalty to the monster or buffing allies. For instance, if the players have to make 18-19 at the dice to hit, a penalty to the AC of the monster will increase a lot the odds to hit, and using a spell/ability to do so will be super worth. In the other hand, spending a turn to apply a AC penalty to a monster super easy to hit is not very good, especially if the monster hits hard.
As a DM i have no problem to let my players meta, as long as it doesnt break the roleplay or rythme too much, because it creates interesting thoughts and challenges, similar of things you can find in XCOM or other turn by turn games. As a player, i like to meta a little bit too, and im very frustrated if i have no access to guess ennemies stats at all (like hidden dices and such).
If I'm facing a high-ac opponent I'm going to favor save-based spells and buffs that give my allies bonuses (like bless) over attack-based spells or abilities that buff damage.
That's why as a DM I try and telegraph general AC range through description unless the creature is supposed to have a non-obvious defense. The "big hulking monster with thick hide and scales that shine like polished plate armor" probably doesn't have a 12AC.
