From what little we've seen in preliminary patch notes and role actions, Frontlines is getting a ton of new options for aggressive play.
When Dragoon, Dark Knight, and all of the other "good" classes got their damage nerfed, we received no alternative options for offense. People have still found a way to make impactful plays, but it's just the same thing with a bit less oomph.
These new role actions, especially Rampage and Dervish, seem to promote new ways of attacking with and supporting your team. Combine that with the Battle High changes that allow the buff to spread more evenly across your team, and I think the devs are finally understanding that offense and aggression keep the game engaging.
I hope that the unseen role actions also encourage people to coordinate attacks with a group, and that Secure turns out to be a great place to play with my friends.
