The D20 system is indeed awful, and the reason why I don't at all care for D&D mechanics. It relies far too much on random chance at the expense of the decisions and choices the player makes in creating and roleplaying their character. That said, the gawdawful D20 system of D&D is still like a million times superior to Larian's Divinity games systems and mechanics. Those systems are utterly simplistic, superficial, and trivial.
