I guarantee more people would play a more strigent 5e mode than play dragonborn, halflings, gnomes, and half orcs combined. Or will play warlocks, sorcerors, druids, rangers, or monks combined. Ordinance the bottom half least popular romance options. Core rules, by definition, are part of the core game. Without them there'd be nothing to play. Lol
Adding the option for star/hp rolls for example would effect ZERO people who don't choose. Changing racial stat points affects EVERYONE.
Why are people defending the lack of options when larian brags about giving options and originally bragged about "95% compliance".
A lot of people won't choose easy or 'tactitian' mode. Guess they should bother. Might as well get rid of all races but humans. All classes but fighter,mage rogue, and clear. Only give access to swords. Etc. Etc.
