True. In WS skill will be much more of a factor. Because of this it will allow for much more room in what is considered "Best Build" since the top players can build so that their playstyle compliments their build and the down time they need to include from moving jumping and dodging.There could still be something that is mathematically best. The difference would be whether or not is executable. Players could have wildly different dps with the same build because of skill. That was true in WoW also. Even though everyone who knew what they were doing specced and geared the same, some still couldn't produce.
