It's called Go Faster because the main changes are to Supers that charge 25% faster and then when in your Super, Titan and Warlocks are faster - Warlocks Dawnblade is utterly ridiculous. You should notice slight differences still though in PvE, especially because many guns, like Pulse Rifles have been buffed considerably. Try Vigilance Wing. Also, the Dragonfly perks is much closer to the explosions on Firefly in D1.
Hand Cannons are also worthy of trying out, although I probably won't join you on those because i'm more of a play and spray type of guy
