Come on. There is no big unbalance here. Yes, some things in this game can be made easier by using your head. This doesn't make anything people do wrong and I wouldn't even call it cheesing. This type of game lends itself to do these things, due to being able to directly manipulate the environment.Then why would anyone bother trying to balance things? I have never seen anyone who shares your opinion successfully answer this question.
You can't 100% balance ANY game, let alone a game like this. People will always find means to make their life easier. Let them do so. They are not harming or hampering -your- game experience in any way. No one has the same kind of skills. "Balance" one thing out, some people find it harder, others find it easier. Everyone's different.
Whining about a mouse fart is what this is.
*Oh no! People are not playing the game the way *I* want them to! This needs to change!*
Who made you the chief of Terraria? How selfish can one get? Flabbergasting.
