Actually, one of the minor changes i was going to make was going to be changing the name of Assassin to Jackknife. I felt the name Assassin and the association a lot of people would have that goes along with that name does not do that class any justice. And especially since facing is not a game mechanic (so no backstabbing from behind), and I'm not about to create mechanics for it just to serve one class, then it really made sense to change the name to something else. Plus, Jackknife sounds pretty awesome.
I've never played Assassin's Creed, so I have no idea how any of that would even work for me.

Finally, you can see from this document that I have taken out the thief pickpocketing class. It didn't end up being fun in the long run and the special ability wasn't that good either.
