Empty, they weight around 90 pounds, and full they weight around 600 pounds.
In the game these common usual barrels weight 10 pounds.
And the "That's no big deal, because players don't have to use them if they don't want to" is the kind of excuse that can be used to implement whatever flaws in gameplay, lore, or mechanic:
- How about putting infinite attribute points at player's disposal on character creation?
A: "That's no big deal, because players don't have to use it if they don't want to."
- How about a portal opening on player's camp, and having a demon giving explosives with no weight and automatic crossbows, so everyone can cheese the game more?
A: "That's no big deal, because players don't have to use them if they don't want to."
- How about putting all magic scrolls inside an infinite bag of holding on the beach, so the player can access all of them on the beggining of the game?
A: "That's no big deal, because players don't have to use them if they don't don't want to."
And the list could go on for a series of absurd things, that could easily be defended using this same flawed logic.
These are all excellent points.
Yeah I think the argument of "just don't use it" falls apart when you subject it to these sorts of escalating absurdities. I mean the whole point of having good world building is that the world feels - even with magic - at least somewhat realistic, or that there are non-arbitrary rules that you have to work with. Any exceptions have to have a story-driven reason behind them.
And even in D&D there is a way to be a barrel-tossing lunatic- but you need to build your character around that.
The point though seems moot as I stated earlier - as Larian applies the RAW - Barrelmancy goes away on its own. I am seeing it less and less in Multiplayer because its just not worth it to lose that kind of inventory space for a single barrel that can't be thrown anyway.
