New "Assassin Class" and a possible new playstyle idea ;)

[Gashy]

Sounds like a fun play style, imagine this though:

You're an assassin. You've been sitting behind a hard mode wave, ready to take out one of the enemies while the rest of your team camps at a shieldwall location.
You shank your target in the back, the rest of the hard mode enemies turn around, and it's gg.

Unless you can stealth and run away (fat chance), I see much impending doom.
