I haven't ever bought anything in game, if you buy materials or weapons or armor or telemetries you are a scrub and rely on buying stuff and not actually earning it like a true gamer and pro. You scrubs are the plague of Destiny and are too scrubby to earn anything.
Edit: If you weren't aware, I was making fun of everyone who thinks buying exotics is practically cheating.
