You are wrong. You were not part of the early access and you have no idea how frustrating it was.
Some of us played the game for hundreds of hours and took as much of their time to write feedback and suggestions.
Unhappy players would have gone if Larian had simply bothered to answer rather than ignoring the questions, expectations, frustrations of the players on the most important threads.
The negative (or "toxic" as toxic people like to say) players are passionnate about this game for 3 years. Appreciate what it is doesn't prevent to be frustrated because it could have been better... especially because during 3 years most complaints were about things players are now complaining about (unbalanced / broken mechanics leading to a very easy game, camera, buggy chain system, inventory management, lack of informations like class overview in character creation,...)
Right, remembered another thing!
- the grove battle still happens in broad daylight against all sense and logic despite people saying it's dumb and arbitrary for 2+ years straight.
At times it also feels like they'd listen very selectively, what with ignoring people who wanted at least an option for the old racial bonuses, deities for paladins, choice of starting equipment, and so on. The resting mechanics and the way switching the party works feel extremely half-baked (the former seems like it wasn't given much thought past its original "fixing", and the latter heavily implies that having everyone in the party at once was a change decided on very late). And all the changes in the writing have been mostly for the worse, honestly (Wyll, the dream guardian, Minthara).
The pre-release showcase was probably the herald of all the sudden changes coming on release, and then the people who'd only picked the game up then would arrogantly say how the EA crowd is stuck in the past and is barely a part of the audience compared to everyone buying the game then. I guess Larian thought the same.
