In my opinion, buying it is the real way to earn it. I didn't get lucky and have it dropped into my lap after an activity. I had to complete nightfalls and weekly level 30's to earn the coins to be able to buy it when I get home from work. By your logic, I didn't "earn" anything I own in real life because I bought it with money I worked for, vs being randomly gifted?

No bounty=luck or purchase

No one gives a shit

It does feel better to earn exotics, but everyone should pick up an ice breaker while they have the chance

I got it from a tiger a day after he sold it the first time. I wanted the sniper but was broke on coins. I was so happy
