Tiny Tina's Assault on Dragon Keep: A Wonderlands One-shot Adventure

Here is a video of me that I took of me destroying the dragons.
You are going to have a much easier time using the gunzerker.

This is the gear I was using, you might have to farm a little bit to get the gear that I have. Also the skill points I have in my skill tree helps a lot.

Gear I am using
-Flakker
-A random torgue laucher (any high damaging launcher from torgue is the best.
-Antagonist shield
-Quad
-Grognozzle (Great at slagging enemies)
-Any class mod that helps with the skills points in tree (especially money shot)
-Any relic (recommended one that that increases reload speed/shotgun damage
-Magic missile (best at slagging enemies)

Just look at the end of the video and you will see.
