Listing those things wasn't meant to say they'd been recent additions or that any of them alone are OP. I used to play an assassin when you could assassinate mobs. I know a lot of it has been there forever. Just making the point that they have something for nearly every situation. But, unlike the saying "Jack of all trades, master of none", the assassin is a "jack of all trades, master of a few".

The shield block mention is just because I think that all thieves should get it and am bitter. Also, the IMM xp req on DVx1 should be removed. :)
