Really BG3 has a system similar to Pillars of Eternity with limited individual inventory for immediate use an always accessibly unlimited stash, but it's just clumsily implemented.
I’ve never played that game. How accessible is the unlimited stash? Can you both send and recieve anything to and from it?
Still, I admit there’s more to encumbrance than what players can pick up. If Larian only care about limiting what’s available to players in combat, then the system works fine. (Except they should heed OP’s advice and remove that annoyance).
