this is an absurd way of thinking, you aren't "earning" anything in this game. Random item drops only block content and slow progression. For a game thats a pretty mild challenge at best not being able to trade is only blocking players from content while they replay the the same levels over and over and over again. Its like working on a factory line and haveing your name be picked out of a hat to get a cookie. The reward has nothing to do with the amount of effort you put in, you only got it because it just so happens your name was pulled from a hat on the same day you bothered to go in for work.
