Pfft earn it? You don't earn jack shit unless its from an exotic bounty kid. The rest is all just RNG. I'd consider buying it to be earning it cause you scavenged the currency to buy it. The rocket launcher is meant to be OP! It and Ice Breaker are the only good exotics left cause all the others have been nerfed to uselessness cause of whining trash like you. Drink bleach kid.
