The tons of loot containers is a big issue for me. It feels like they literally only exist to bloat playtime. It made sense to have them in DOS2 because you had a chance of triggering Lucky Charm and finding rare loot in every container, but no such mechanic exists (or even should) within BG3.
There's also the angle of the fact that someone had to spend time programming all these empty loot containers. Like... Why?
