DU is the only origin that gets the incredibly OP (even if it is somewhat bugged) cloak that can give you you invisibility once per turn. Gale gets a moderately useful ring that no one else does. I can see how missing out on loot can make people not want to play a certain origin character. Making it possible to get any loot on any character would probably be an improvement. Maybe a special vendor or new game+ that lets you import an item from a different character once you finish the game.
This could also let people play how they want (peaceful playthrough, throwing people off cliffs, pick different sides) and not worry about missing out on loot.
