Firstly, for those reading, here is the link to the Obroan PvP armor sets. The PTS notes state that these models are still placeholders and could be non-final and still subjected to change, which is why I'm posting my suggestion to swap the Jedi Knight and Sith Warrior sets respectively.
Overall, I think that the art direction is great for the theme - Dread Masters - and the sets have improved in comparison to previous armor models. I just believe that the set assigned to the Jedi Knight is completely off and should be swapped with the Sith Warrior set. The reason I propose this is because the Jedi Knight set does not look right for a class that is supposed to fit the hero archetype. The Sith Warrior is comparatively the opposite in every way to the Jedi Knight class and the set assigned to the Jedi Knight looks sinister in nature (which is not right).
Feel free to leave your support or protest against my idea, I am interested in what the community has to say!
