1.3.1/1.3.2

Why did Mojang add emeralds to the game, i mean what is the point of it if there is no armor or tools just trading. I mean it's so stupid and how people on servers are making so it cost 1000 dollars just to buy one. Now onto side way's wood, REALLY how often do you see a sideways log on a tree in real life. Now onto lamps, Why are they on trees in real life do you really see lanterns on trees i don't know why the drop cocoa beans either it's just so stupid. That is all i have some of you will agree a lot will disagree.
