The Survival overhaul is supposed to add a ton of new mechanics, like hunger, sleep, diseases, disabled fast travel; do you think they'll add some new functions to the existing perks to tie into Survival? Like, if they're disabling fast-travel, the last rank of Strong Back is essentially useless for anyone on Survival (I've already avoided it on a character that I never fast-traveled with in the first place), so I imagine they'd try and change it.
Then there are other perks that have questionable use in the game as it stands, but could totally tie in with new mechanics added in the survival update. Awareness could tell you if an enemy has a disease, or VANS could point you to the nearest bed/save point if you don't have any active quests.
On hunger: You know what would change my play habits more than just a meter tracking my hunger? If they actually limited how much food we could eat at once - in this game and New Vegas, it's pretty simple to get past the heals-over-time mechanic by scarfing down a wide variety of different foods and having them all stack. Then they could have ranks of Lead Belly increase how much we could eat at once - as well as reduce the risk of contracting a disease from food/water, and affect how quickly hunger even sets in. I'm fully expecting there to be a unique and slightly-funny disease you can get exclusively from pre-war food.
(one of the things I'd have liked to have seen from the beginning is Endurance having a small multiplier on how much food heals you, but que sera sera)
You think they'll change any of the perks to tie in with what they add in Survival Mode?
