I think you just figured out why no one plays the Starviper.
It's going to be an arc-dodger. Being better when you get caught jousting doesn't beat never being shot at all.
What are you basing this on, the action bar having boost and barrel roll? The Starviper has both of those actions, but is more jouster than arc-dodger.
The actions available are only half the equation, action efficiency is the other half. Without the greens to enable PTL or some other mechanic, they won't be utilizing those actions.
Thematically, I think it's more likely that they are close in knife fighters. I could see a lot of short s-loops, k-turns, and talon rolls to enable them to constantly be facing their enemy. I would bet it's as likely that this is the first ship with both and s-loop and a t-roll as that this ship has a green hard turn.
The preview article says that this is supposed to be an aggressive jouster, but with no shields, and a spoiled pilot that just needs to get close the clear choice is dodge arcs and let the title forgive times you can't. I think the Fang is going to be the new hotness of wave IX.
I'd love it if it had the Starviper dial but with green 1 turns, 2 Speed T-Rolls and a 5-K. That's a lot of maneuvers for one dial though.
