Yeah, stealth being broken is absolutely intentional. Larian desperately wants to give the player advantage on every attack, not only because it largely trivializes connecting with a target but also because it effectively removes the vast majority of debuffs in the game, which impose disadvantage on the player. But, it doesn't stop there! In this game, stealth is the ultimate offensive and defensive strategy. It provides invulnerability at the cost of a bonus action. To the enemy AI, the player ceases to exist when hidden.
Swen said in a presentation that they take great pride in 'broken' mechanics like this, as it makes the player feel 'clever' when they discover them, though I can't imagine why.
Did he really say that? Do you have the link for that? That doesn't sound like Swen, but who knows.
You know there is also the hope/possibility that we will have a "core rules" option for Bg3, just like Bg1 and 2 had.
