My hard light was my first exotic in the second week of the game. Did I deserve or earn it? No. It was randomly gifted to me through a RNG game. The people who get hard light from xur have earned theirs. The ones who already had a hard light, or any other exotic that xur then sells, were randomly gifted it. The people who actually tried hard on earning their 'written-in-stone' strange coins rewards from weeklies, earn the exotic. They put work and time into it. The ones who are gifted by random, don't earn it.
