Nah , if you ever played games such as WoW, Ragnarok, Rappelz , or even Diablo2 (even though its half assed) you will notice that they all put similar aspects in the Assassin class. Such as Transperancy, High Flee , Critical , and Fast Attacks.
In my sence of though, you would think they would do the similar approach but maybe more work into the skills to truely make it a Stealthy deadly approach. A lot of games usually forget to keep on track on this class, most players are looking for assassin class to be a class to be reckon with. Such as you havent to stop its close range barrage, or be killed. Now those are truely aspects of an assassin that are truely remakable.
