Everyone should stop complaining about Xur selling the red death, why? Because any skilled guardian will kill you, no matter what weapon he has. In a gunfight, a more skillful guardian will triumph no matter if he has red death or not. On the other hand, a noob guardian will not kill you with any gun if you are skillful enough to maneuver around the map and dodge incoming shots. If you have the accuracy and maneuverability, you will triumph over a noob with red death. Therefore, the only thing that will change in the crucible is the amount of red deaths flying around, if you are skillful enough and are a day 1 player as I am. Then you should not worry.
