Burning gratifying laser sploder farming problems

anyone else having a problem getting this weapon I’ve put in about 30 hours farming this guy off the loot minion and i think I’ve got pretty much all of the good legendary’s in the game except the one i want lol. Anyone else having a problem getting this one i mean I’ve even thrown on the artifact that takes away 75% of my life and I’m on mayhem 3 i get around 3 legendary’s each time and i still haven’t gotten it

It exists and its just luck , I have it shock/corrosive/fire.On the note how rare it is , well … no one can answer that.World drop.

does it only drop in vault hunter mode?

No it drops in normal aswell

thank you for the response im just gonna keep farming and hope they dont nerf the drop rate again and ruin it or me.
