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.
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.
It's not very helpful to make blanket statements like this or to be fundamentalist about a particular set of rules. Honestly, how many other rulesets have you ever played? 5e isn't considered the best ruleset any more than Coke is considered the best drink in the world. I've played about fifteen game systems over about thirty-five years of gaming. I'd choose almost any other system than 5e for my campaigns. It has the primary merit of being widely known, allowing Larian to reach a wider audience.
