I (...) (...) Solasta chose the path to make their game more accessable to have a lot of toggles so you can actually tailor the rules and make it either to an authentic dnd5e experience or just a more simpler version, which i think is a good approach. I hope Larian will do something similar.
For fun, one of the things they removed in Solasta (mid-January 2021) was actually a *homebrew* rule they had implemented that made lack of light more hardcore. Characters in dim light without Darkvision had a rough time (Disadvantage on attacks. In vanilla 5e, Dim LIght is Disadvantage on Perception checks only; not to be confused with darkness, heavily obscured, etc.).
I do see the following in Solasta's settings : - You can choose to change Prepared spells without doing a Long Rest (by default, it respects 5e rules) ; - Spell components : for each Verbal, Somatic and Material component, you can choose to disable it, make it basic or full (eg. full: you need a free hand to cast and Revivify cost 300 gold of diamond dust).
