My GOD!! Someone just gave me a Redundant (double shot) Luck Cannon. And I have to say, this thing is Ridiculous on Claptrap. (Start with a Bang + Load’n-Splode + One Last Shot + Killbot) + Sapper Mod + Redundant Luck Cannon = Insane. Pair it with something like the "Naught"Shield, and let the fun begin. Really, this takes what every Explosive build Claptrap has been doing forever with Tediore weapons, and replaces it with a Weapon that can smack you in the face with the force of a Launcher and do it twice as Fast.
(Note, still trying to figure out if the Redundant Luck Cannon is legit or not, the fact the guy had some many legendary, so soon, makes me wounder, but even if not, this is still insane).
