(change) assassin T class

[goet]

as it is now, assassin is the worst possible class to get as a T. +damage to peoples backs is near worthless, if you're in a position where an inno is facing away from you you've basically already won (barring bad luck or gross incompetence), while -damage to the front is absolutely crippling in any kind of fight where people are actually shooting back. if both these traits were dropped the class would actually be pretty cool, even with the headshot damage vulnerability.
