For those of you who don't know, or haven't heard, one of the rumored features for Survival, is no fast travel. Usually, there is no problem with a gameplay change intended to increase difficultly. However, rank four of the Strong Back perk will become useless. It allows you to fast travel when over encumbered. It is also rumored that when you are over encumbered, you will loose Endurance, Agility, and may cripple limbs. I think, that Bethesda will change the perk for Survival to remove these side effects in Survival. What do you think?
