actually in WoW and this was even on a g4 thing a year ago. Jump in WoW got you to hidden places in the game. For perfect world international there was a quest that required you to know how to jump as they had tons of locations.

And skyrant
that whole fence thing is not even true. Fences are just for decor. Not to keep you out of something. I hated rollanberry feilds because of those fences getting around them was a pain. And more so in wings of the goddess cuz of the high lvl qudev, which kill lvl 75s easily. blocked the only route around them. if I had the choice between jumping over a fence or getting attacked by something and dieing... Ima jump over the fence.

And pretty much your whole post is one invalid rant that really just scream hating just to hate.
