I dunno, this seems like a weird take to me. Personally I love Elden Ring and most of From's games, and am simultaneously very critical of BG3. It seems a little bizarre to me to claim that the sort of people who get upset at BG3 are the same people who can't git gud at Elden Ring - in particular because BG3 is an absurdly easy game.
Yeah, I'd like Bg3 to be more challenging as well. However, that isn't a common experience. The majority of players find it very challenging to the point of frustration even on Balanced Difficulty.
What that really tells me is that gaming companies have been afraid to challenge their players and have been cheating them out of the experience of overcoming difficult scenarios.
