I don't agree that modern RPGs have a different standard - I feel like exploits are inherent in any games with complex systems and a high number of interactions. And we see that with tons of modern RPGs. Whether it be abilities and spells, environment objects/actions, as long as there are sufficient options, people will find a way to combine and exploit it.
Again, the problem isn't with BG3 that OP builds exist but that basic mechanics or basic interactions dont' work very well. Finding a way to "break" the game can be satisfying in itself if it requires explorations, some thinking and learning the systems. BG3 foundations are shaky. Push, stealth, combat bubble, current implementation of action econmy and its implications for multiattack on later levels - those are not things required effort to exploit, it things that just don't work well and need to be improved.
