Larian Studios Forums Divinity: Original Sin 2 Divinity - Original Sin 2 - General Other skill trees as Patch/DLC?

This is not true for at least a good number of them, Bard especially.

I think that some of the talents which were intended for the other trees which didn't make it could be added to D:OS 2. Such as the Berserker talent which increases your damage as your health gets lower.

Very true.
