The design philosophy is so fucking warped on this game it really makes you ponder. Why cut down 90% of the mechanics and remove things like classes, rolls and itemization and remove party creation, because I assume they wanted to appeal to casuals, but then decide to go with a strict checkpoint system for saving? It's just... dissonant.
Again, cut down what exactly. Maybe you care to elaborate? The old games have been as simple as it gets already.
You still have classes (fewer, admittedly, but you gain skills to differentiate them, which was not possible before) and itemization is worse now why exactly? It wasn't that meaningful to begin with, imo.
They did remove most of the RNG, true.
Also you have far fewer spells (most of which were useless or redundant anyway, though).
Still, I don't see how they have dumbed it down so much, here.
I would find it more convincing to argue that they have not used the chance to actually introduce some proper ruleset to the series...
