This thread did not ask for double XP for horde, we specifically do not want static XP, instead we want progress based XP which rewards survival. I would be happy with 10XP for casual Horde for wave 1, and it going from there to prevent farming waves 1-4 and instead encouraging teamwork and playing the game in the spirit in which it was intended.
This thread also has nothing to do with the Shotgun, or anything going back to Gears 1. Neither Horde nor XP was in Gears 1 on the 360. Horde like mods were made for PC, which were awesome.
Maybe Epic should stop letting "you people" post on the forums because nothing constructive happens from posting things that do not make sense.
