You don't earn strange coins. They are free to anyone who can beat a heroic strike that has a whopping 2 modifiers (1 if you exclude heroic), that isn't earning and you know it. Grinding your ass off for weeks for that random "lucky" drop is hard work and well earned. The best guns and gear in this game should not be handed out to anyone who can beat a f*cking heroic strike 3 times. You're entitled to think you are owed this opportunity, in any other RNG loot game you aren't handed the best shit like that.
