There where cheese tactics in bg1 + 2 also (for example trap stacking). However the massiv difference was that it never intended to be used this way and people just came up with weird ideas on use of spells and ability’s that devs didn’t see when they made the game.

In bg3 larians devs are fully aware of the cheese and put it into the game intentionally because they think it’s fun. And since they’re history lies in divinity games and not DnD games it’s not much of a surprise. And because they are not DnD gamers no one will ever be able to convince them that they are wrong in this case.

This is why so many people say the license should have gone to an other company for the sake of DnD.
