D&D exists for about 45 years so yes, it's a bible and it looks like the 5th edition is really appreciated by role playing players. I trust them and I'd lobe this game to become a true BG and D&D experience.
I didn't realize all of those players were still playing the unaltered first edition, I guess it really is hard to improve perfection though.
BG 1 and 2 started from the table top rules and adjusted as was *necessary*. They became two of the greatest RPGs ever made, to the point where a major studio is making an unbelievable popular sequel 20 years later.
BG 3 is starting from DoS 2 and incorporating the bare minimum needed to make the game sorta seem like a D&D game, but in name only.
The rules of 5e have 6+ years of playtesting to support them in addition to baked in added content. DoS 1 and 2 were great and fun games, but their balance was laughable, to the point of being meme'd into the ground. If you think you can design a better rules system for an RPG go right on ahead. But there's a reason 5e has absolutely dwarfed every other RPG in the market.
5e has 6+ years of playtesting and support as a tabletop game, claiming its history somehow validates it as a crpg is nonsensical. I'm also not sure how to tell you this but BG 1 and 2 were far from balanced and that can't be made more obvious than by the fact that you had to cite their fame as crpgs and not their fame for game balance.
