I was on a server yesterday ... name escapes me, but it was something like "Dark Lands" ... anyway, the admin had done soemthing to allow the use of "part" of the patch data ... modifying the weapon damage, but not changing the way the swings were done (i.e. med stance still had all the spins, but for the reduced damage) ... and heavy stance had the new moves instead, yet med, fast had the old ones/speed. I asked what he did but he told me it was a secret, bull**** or is there some way?
unfortunatly I do not remember :-/
On an unpure server, you can mess around with pretty much anything. I avoid them at all costs for that reason and the fact that there's nothing stopping people from using wall hacks, etc.
