I can't believe Preypacer and one or two people are basically the only ones with reading comprehension skills... or with a little common sense.

I'll end up basically repeating what's been said already since people seem too thick to grasp it:
  1. This thread isn't against jumping.
  2. In fantasy settings the rules of realism are reestablished based what is believable (which is sustained by logic). For example: A wizard harnesses the elements of nature and casts a spell, depleting his mana. He is out of mana, so he can't keep casting. If the wizard were to cast another spell people would cry "no way, he's out of mana!". But they wouldn't complain about the fact it's a guy using magic.
  3. The tent has been modeled to mimic fabric's consistency (you can see it in the folds). Having a bunch of people jump up and down on it is a direct contradiction of what is being shown. Thus it becomes unbelievable in a fantasy environment.
  4. Yoshi has already stated that invisible walls are being positioned in cliffs that go nowhere or that are too high to jump. So the concept of invisible walls IS here. It IS being applied.
