Not sure how competitive this is, decided to chunk my Raven Guard, I was too serious and want to return to my roots of Orks! Fun and laughable even when you fail charges

I plan on going to a local tournament in 2 weeks with it and Alamo
GT in May. Comments and Critique are always welcome or changes. I own all the models and can swap things around. I want to keep the Dread Mob at exactly 1500 points though.

I know it's taboo to take 2 Rokkits on the Deff Dread but keeping it at 1500 points for the formation. The Tankbustas are suicide squads. Will be fun and full of laughs. Let me know what y'all think.
