They think the mini-game of "avoid vision cones" is more fun for stealth than using RPG rules. So much fun, that bending the rules and reality by excluding sound completely from the equation is worth it. It's not.
Why I think BG3 stealth is really bad is that it emphasizes player skill over character skill. And in this case, a trained chimpanzee could avoid the vision cones when time is literally stopped for the enemies in turn based mode. It also completely devalues a stealthy Rogue, when a Fighter in Heavy Armor is just as sneaky as long as you don't end up in a "vision cone". Everyone getting to Hide as a Bonus Action devalues the Rogue's unique abilities and flavor even more.
I think "vision cones" is a fundamentally bad and flawed mechanic, especially in a turn based game. And in a game where characters have skills to govern this aspect of gameplay. Someone walking forward would easily have a 180 vision cone by just looking left and right while walking. And a 360 sound sphere. Someone who is alert and actively searching should have a 360 cone.
The most braindead scenario is when you circle behind an enemy in melee and "hide" as a BA and then attack with Advantage.
Why would a fundamental feature like Stealth be unfinished after almost two years in Early Access? Clearly they prefer their Vision Cones mini-game instead of the 5e system. The only fix or improvement I would expect is enemies moving towards the last position marker instead of just sitting there getting killed.
