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.

Then choose where you [i]work[/i]. The activities dictate what you get, hence you replay the activities with higher yields of items you want. It's not as random as you're making it out to be. In the end the content is there and you [b]will[/b] eventually get something when you accomplished something. The RNG is going to be unbiased in its distribution. Trading does seem like a way to get great items in more peoples hands but it also saturates the game with good gear to just about anyone. I'm not saying the way it is is perfect but I prefer it.
