If you grinded the weekly heroic for you coins, then yes you earned them and have a right to go buy something. There are 2 different ways to get gear in this game: Earning and RNGing Earning is when you earn strange coins and go buy something from xur. You could relate this to having a job irl and getting money to pay for food RNGing is when you get anything from the RNG. Either being afk in the crucible, afk in strikes, skipping all the enemies in strikes, or any endgame reward. Even the bounties are RNGing. You have to get them through the RNG, hence its RNGing. You could relate this to a homeless bum who is outside in the cold with a tin cup begging for money. Someone walks by and a $20 falls out of his pocket. The homeless bum doesn't earn that cash as he grabs it before the original owner could get it, but then he gloats to all his friends that he "earned" that $20
