ST should add some kind of evasive maneuver. Heck, even those rogues in Linear Train can do dodge rolls. The animation data is already in the game, just add it to players and map it to our unused PA button.

But frankly, this is something that should be added to every class. The game itself lacks any possible defensive action other than "tilt the stick and hope you run out of harm's way in time". And blocking is not an action. At least not until AoI.
