You honestly make me laugh at how utterly idiotic and immature you are. Someone simply opening a chest after begging to get the checkpoint is honestly earning it more than working through a weekly heroic (which sometimes is a lot harder than the Nightfall mind you) to get strange coins to buy the exotics. It's called balancing things against RNG. That is why Vendors sell legendaries, but you can get legendaries from engrams as well. You wouldn't say that the person who earned the marks and bought a weapon with it didn't earn would you?
