He stinks early on but later is debatably the strongest class. Kreig is my favorite character and class to play. (Since out of bubblegum will give me a flat 70% increase in fire rate all the time, then there is keep firing 88%, and locked and loaded 50% for a total of up to 208% fire rate) I might switch out some fire rate for reload speed, not sure yet though. My damage won't be spectacular, but the rain of bullets will more than make up for it. Then I can gunzerk and flip them off again lol. Since I can only use come at me bro once per gunzerk i am not using anything to extend it's duration, but taking decent steps for it to cool down faster.
I will have over 350% damage resistance (for about 8 seconds anyway), it sounds high but will only be reducing the damage by about 78% (dang you diminishing returns). I will be using a Titan Class mod (Legendary if possible) and a rough rider shield, and a resistance relic which will further make me resistant to damage. I am still fine tuning it but I am aiming for max damage resistance, health regen, and fire rate. Still up in the air about what I want to do but the build I am planning looks something like this. I am going for more of a tank build so I won't be in fight for your life so much on UVHM. Although I would invest in Inconceivable so you have a chance of doing more money shots.
