Can someone help me to power level my gunzerker to lvl 80

I need to level up my gunzerker to level 80. It can be a XP glitch or whatever. I can do the OP levels my self. Gamertag? AleBOI1206.

Hit me up. Gamertag is ValkyriesHero

I’d like to be apart of this too if it’s not too much trouble, my current level is a 43 psycho and my gamer tag is Mini Stavy, Thank you
