This looks fairly close to the rather rare hybrid Brick builds you can find elsewhere in this section, a few things:
Sting Like A Bee is practically mandatory for using berserk as a major component of your damage output, it’s incredible helpful for sticking to enemies that shooting you as being hit slows your movement slightly.
I would actually consider ditching Short Fuse for this Hybrid build since you plan on using Explosive weaponry and already have Liquidate (which can get Berserk off cooldown faster than Short Fuse if you utilize it well).
I would also ditch Juggernaut as it one of the weaker skills in the Tank tree (despite being a decent all-round skill). I would instead put those points into Die Hard (which is imo, just about mandatory for all Brick builds), and works nicely with the Hybrid build.
Move the points in Rapid Reload into Revenge, early game you might stick with Rapid Reload, but once your weapon proficiencies start to get decently high (they max at 50), you will be getting a large reload speed buff from there, and thus the marginal benefit of the reload speed from Rapid Reload is greatly reduced. Revenge does not affect Rockets, but instead all bullet firing guns (and it’s a VERY powerful skill).
Wide Load is optional depending on how much use you plan to make of Rocket Launchers (if you’re expecting them to be like Borderlands 2 RLs, you will be disappointed, though they are still effective against most enemies). I would max out Liquidate, and move the points from Cast Iron over to Master Blaster (seriously OP fire rate buff on that), and would put the last 3 points into Wide Load (making that the 3/5 skill).
