The new subclasses coming in Baldur's Gate 3 are a powergamer's paradise, and I know because I've seen them do terrible work in D&D
The Path of Giants barbarian, meanwhile, is a funny old one, because I predict it'll be busted in Baldur's Gate 3, specifically. In 5th edition, the subclass gives you the ability to return your thrown weapon to your hand starting at level 6 with a choice of elemental-typed damage, as well as a bonus to your thrown weapon attacks even earlier.
