As with most things Larian changed, they should have started by iterating on 5e and its design/intentions, rather than changing chunks wholesale. 5e isn't perfect, neither is Solasta. But Larian could have iterated and polished things to create an improved version of 5e, rather than making numerous clumsy changes that end up having knock-on effects which require more changes or just generally end up leaving stuff broken. Do people who are against the Solasta method really think that it's the ultimate version of that approach and thus cannot be altered or changed to be more palatable or have more flow? If Larian is good enough to be given this license, they should be good enough to improve on the reaction system, rather than just replacing it wholesale and altering everything connected to it. Furthermore, 5e has its flaws, and there are folk around here who understand that far better than me, but surely they aren't so great that talented devs couldn't improve them, rather than just replacing them outright, seemingly without a lot of initial thought as to what the effects of it on overall balance will be.
