I know you wish really, REALLY hard for people to agree with you on this, but for the vast majority of players who are actually familiar with both games that's absolutely not the case.
You are mistaken. a vocal minority is not a vast majority. Solasta didn't even implement any reaction-heavy class, because it's reaction system is so bad having a bard will turn the combat into pop-up hell. People praising Solasta's reaction system are a very niche group of obsessed 5e rules fans who derive some perverted masochistic pleasure from enacting a clunky and unbalanced DnD 5e ruleset in a videogame. DnD works in a real-life table-top environment because it only serves as a foundation for DM's story-telling, not some Holy Scripture of Irrefutable Dogmas.
