That's fair I guess, although the fact I haven't yet reached the expert loot cap and that in itself is only 70% of the total loot is a bit surprising. I normally play on the hardest difficultly of most maps simply because they're going to have the most objectives and requirements, so it's a way to force myself to work harder to achieve said objectives. That said, some people set their loot objectives as optional rather than mandatory, but that's mostly an argument for whether the player should have just selected an easier skill level.
If this was Deus Ex: Mankind Divided I would have just enabled that augmentation that allows you to see lootable items through walls and be done with it, but I think it just ends up making me suck when I have to do it myself.
