Yes. This is exactly the reason for why I think that Kaijan's DPS result is a very good reference. He/She stated that the dps could have been slightly bigger if there hadn't been a few small mistakes in the damage rotation. But there never will be an ideal fight where you do not make a single mistake. With this class it's much easier to make a (very costly) mistake if you mess up your rotation than it is with any of the other dps classes.
So the dps result accounts for the fact that the class is more diffult to play and that it leaves more room for mistakes.
Heh, who knew that me screwing up could be a good thing =P
