Oh Dita is
Oh no man, I would say Dita is in no way a generic gunline. (I might be biased here ) Once you learn her she is incredibly mobile and often times likes to be right in the middle of ML. I honestly find Sonnia to be more of a static gunline (well fireball line) than Dita is. She often for me acts as a slow-moving turret in the center of the field while Dita is zooming all around shooting stuff in the face.
@Ozymandias79 I agree Hoffman can run very well with pure guild. Its just the versatility of some of the Arcanist models. They are just extra tools in the Hoff's toolbox.
