Are you certain that there are "rare" walls in Quick Survival that don't show up on the regular shows.
I played Quick Survival before anything else and I got loads of easy walls. I have since beaten all 10 shows and now Quick Survival seems to be much different, giving me much more difficult walls, but all from the 10 available Shows. I don't think I have seen a single wall in Quick Survival that has not appeared in one of the regular 10 shows.
I was just wondering if you were able to determine otherwise.
I do not mean to call out your guide, I just don't want to pass hundreds of walls in Quick Survival if I don't have to, as I have passed every single wall at one point or other in all single player shows.
