Matt, posting such a step by step tutorial (I mean that makes it easy for anyone) is pretty lame, Model Changing informations must stay as underground as possible, and be not shared with anyone...
Any person who has a brain and is interested in Model Changing thing enough would figure out easily this kind of 'possibility' by himself.
The 'exploit' you give is just a lame (abuse) use of Model Changing, and the sadest thing is that you'll get banned (100%chance) and will push more and more Blizzard to do something against Data editing...which would be a terrible loss, cause Model Changing is best used for fun and exploration purpose, not for getting unfair advantages upon your opponents...
Hope you'll understand our view and edit your above post
