Honest to god, the BEST answer, is that Larian makes absolutely sure that all of this is able to be adjusted via mods. I have absolutely no reason to believe that 'balance' is a concern here.
Simply allow us to fully mod the game (and Explosive Arrows, Spells, Ground Effects, Hight Advantage, and Barrels are ALL able to be modded out) in every capacity, and no problem.
I would MUCH rather that be the primary focus from Larian. Every could be happy then.
Truthfully this is what I think is happening. They are relying heavily on mods to feed the community what they want. If they go this route it could wind up being like Bethesda mods in future games.
