Sigh. Once again we are faced with the question: is this intentional design or did Larian somehow
forget to implement an important mechanic?
What does this mean? Well, honestly, going Dex-based still loses you Barb's natural synergy for big ol' heavy weapons and Great Weapon Master. Hell, part of the appeal of Barbarian is probably being able to throw enemies around with impunity. But, assuming it's not patched out or altered to match PHB, for now it seems the Dexterity Barbarian can more or less be. Thought people might find it interesting.
You lose the synergy of heavy weapons and being able to throw large enemies, true. But you gain the ability to focus on only Dex&Con instead of Str&Dex&Con - which'll effectively add ~3 to your AC, initiative, and Dex STs. Honestly probably still a poor trade...unless Rage affects ranged weapons and you can take Sharpshooter when implemented???
It's unclear what Strength you need to throw what enemies (Can a Str 8 character throw a goblin?), but it is possible that Throw percentages-to-hit an enemy could depend on Dex (as it seems like throwing is an attack roll). So a Dex Barb might have an equal chance-to-hit when throwing goblins into goblins, but just not as far.
