He sold it week 1 and week 4, and not everybody had their shit together with coins. Not to mention all the new players that didn't pick up destiny in the first month. After the buff, Red Death is now a two headshot kill in PvP with instant health rege and a faster reload. It's arguably better than Thorn and Hawkmoon if you use it right. So now the crucible is over run with a borderline OP weapon. Suros was nerfed so many times because it was very popular in the crucible. So what happens when Xur sells a much better weapon when almost everyone has a gross supply of strange coins? Everybody buys one and the crucible (and the upcoming Iron Banner) is flooded with the same two headshot kill weapon. So now you are at a serious disadvantage if you don't use either a red death, thorn, hawkmoon, or the last word. I can't be the only one that thinks Xur selling such a powerful pvp weapon is retarded.
