Not really suprising....it's not like FFXI is super hackprotected...all you'd have to do is tell the client to add a surface here to walk on, raise up the avatar, not too immpossible I imagine. Now, I want to know if it actually does anything server side, because people passed that guy like nothing was happening.
you know if one single NA saw that they'd go "OMG H4X!"
I hope people don't start using this **** to get to Roc and smiurgh without the slightest walk, or worse yet, mass speedhacking to claim NMs.
Although i'm sure when S-E Packs up and the only crew left is a programming team to fix bugs, and a few GMs to get you out of walls, they probably won't care.
