Blount - The anti-swarm.
He's also going to make running a Stealth Device pretty much a waste of points if you happen to be against him and can't kill him first.
Not likely. Most ships that carry a Stealth Device are way more maneuverable than Blount. Biggest exception is a lot of people play Stealth Devices on Howlrunner and Biggs, that may change because they typically have to Joust. Interceptors, A-wings, Backstabber, Vader, they can call easily make attacks from behind Blount. Blount is good, but no game-changer.
