I would suggest that you not focus on the looks of gear. Unless there is a set that you really like the looks of and is only available to one class. Focus more on the animations and style of each spec, especially the spec you intend on playing. While you can always change your gear looks to freshen things up, you are for the most part stuck with the same basic animations of the class. (Some animations have been adjusted and may be adjusted in the future. For example lacerations animation for concealment ops. Tracer missile swapped with fusion missile, etc.)
Uh, wouldn't the Shadow and Assassin have the same animations considering they're mirror classes for each faction?
I guess my question came down to which has a better story (Counselor or Inquisitor), and just a general opinion of them both.
