I agree with error3. The game is cooperative AND competitive. In fact, competitive questing is one of the main features of the game, if I recall correctly. Just look at the plot and the ending video of act 1.
Personally I always play with friends so we don't have too much problem but I see where OP is coming from. The idea of having every player (not character) loot each corpse/crate once seems good but it can cause some issues with economics and relative power of the party. I wouldn't mind if Larian think they can make things work.
On the other hand, the dice roll system is probably the safest route to take. If there was a way to configure party loot just like in a mmo party it would be perfect (Rarity, Master loot or not, deactivated altogether for people like Neonivek)
