The difference is, between us and Larian, only Larian is actually making the game. If both parties are just offering subjective opinions, why the heck would Larian follow our subjective opinion over their own? Especially when we do not represent the majority of consumers.
The majority won't care.
The argument presented is false. 'oh pure 5e is less fun'
They don't know that. They didn't implement it. It's as hollow a statement as the name drop Baldur's Gate.
It's corporate speak.
Also, Solasta is fun, so claiming pure 5e isn't fun is flatly false.
