Which one is more of a gamebreaker: Xur- A NPC Bungie put in for the player's benefit of buying weapons and armor with currency you need to earn weekly (not as bad as marks at least). Someone every reasonable player has turned to to get something they really want or would like to try. Cheesing- A glitch Bungie neglects to fix for several weeks, allowing players underleveled and underskilled to complete the current hardest content of the game. Absolutely breaking any sort of elite status in the game and taking 100% of the challenge out of it (unless you're into self entitlement). Can we please bitch and moan about the real problems here? If you're so "elite" mass complain about cheesing, not some stupid item you can get as soon as you turn level 20.
