In regards to Titania I honestly wouldn't use that as a basis for how the job would play even if any information pops up. E3 is open to the general public so you'll get a mix of people brand to xiv and those who are assuring they get the clear for the shirt. Let alone with it being not at max level it's tough to make a call on it.
I'd say the media tour (while potencies may have changed) is the best source for information as influencers were the only ones there. So those people at least have a better grasp on how the job plays and can offer better information. Until we have the expac in our hands I've been using that as a main root to figure out how each job will honestly play.
