Path of Giants...

[Agent Chieftain]

Do you think it will be better for Throw Barb than Berserker? It will certainly be doing more damage per attack than a Throwzerker, especially because you can make any weapon a throwing weapon with elemental damage and giant form on top. I'll be curious to see if the Gianstlayer greatsword applies the extra strength modifiers when thrown.

But your throw isn't a bonus action like enraged throw is, so the total number of times you can actually throw per turn is always 2 less than Berserker. Plus enraged throw is just a stronger version of throw in general. You also need to commit 6 points to Barbarian for the throw benefits, preventing you from taking some extra multi-class benefits, like the extra crit chance from Champion.
