How so would it cause unfairness. If it's just changing the backround textures to make it more entertaining or whatever they feel then how so is this unfair. This is done in hundreds of runs on black ops 1 and 2 games. What's bad of having it on this game. If it does somehow cause crashing in a run then so be it. But if a run is done successfully with just a bit of funny textures in the backround. I dont really see a problem with that.
