OP Ordnance Overdrive

This build is available in video form here:

Build Summary: We are stacking splash, ordnance, and gun damage to make our thrown guns and nades do lots and lots of damage. Rafa's Insta-Fort Battle System will shoot free nades for us, and his Overdrive ability gives TONS of benefits that can scale even further from Soltado. Just keep chucking nades and guns in the vague direction of the things you don't want to be alive anymore.

Important Skills: El Valiente grants 60% increased damage from all sources while on full shields.
Confeti adds bonus damage to ordnance in the element of our equipped gun- use this to counter type stronger enemies.
Errant Spark and Asymetric Warfare add a ton of damage to all thrown guns and nades.
Barrage increases splash aka AoE damage which is basically all of our damage.
Sitiar and Temerario scale gun damage which increases tediore throw damage PLUS is converted to ordnance damage through Full Spectrum Arsenal.
Soltado doubles most of our bonuses into very crazy ranges.

Important Gear: Tediore weapons to throw (the Chuck is a solid one), a Grenazerker legendary class mod, a Tediore enhancement with extra ammo damage/extra guns thrown, a Triple Bypass with ordnance cooldown. Grenades can be extremely flexible, legendary options are good but so are lots of purples.
