Loot caving is far from cheating. Cheating yeilds success. Loot caves are THE WORST way of getting anything. Even class materials and weapons parts. Farming works in similar games and is needed, but that's not how this game is meant to be played and that's why the results are pathelic. And trading would destroy the game since you can just bum stuff off your friends. Even if they made it so you could only trade the aame rarity tier, it would still wreck the game.
