I definitely think they should utilize magic pockets for the barter system - that seems like an oversight to me. In general, though, I'd like to see Larian really look at carrying capacity and encumbrance in general. As is, I think we are allowed to carry way too much stuff. Where is Laezel holding a couple of crates and a few oil barrels? Those things might be within her carrying capacity (she's very strong), but they are bulky. If she picks up a crate, she should actually be carrying it in her arms, and maybe at a reduced speed.
