You can't just go and decide case by case tho. I for example dont see anything wrong with going through a window with a mount. I think its fun as well. Going under the world is obvious on the other hand. And there are many cases like this. If there aren't exact rules about exploits how are you supposed to know what is ok and what isnt. It becomes stupid very quickly. Oh watercasting is ok, but is stambug on a mount ok to use? Do we have to makea big list with all the exploits that will get you banned? What if someone discovers a new exploit? Can he use it or will he get banned? Where do we draw the line between ban and being ok to use an exploit? Games like Starcraft have a list of exloit everyone uses, mutastacking for example. But its ok to use any exploit in that game, no exploit will suddenly get you disqualified in a tournament. Games need clear rules otherwise everything becomes grey and the whole posting videos about people using exploits is terrible for the game lets face it.
