I've seen a lot of people in various forums wishing that when the new survival mode came out, there was a way to go back to old survival. This fixes that and makes "Very Hard" the same as the original survival mode - stimpaks and Radaway now heal slowly exactly the way the did in original survival mode, and the chance to find legendary mobs is the same as well. 

PLEASE NOTE: From looking at values in the creation kit, it looks like at some point they lowered the legendary chance in various difficulty modes. This mod takes it back to the original 3x multiplier that it originally was in the old survival mode.

This is my very first mod. I feel confident that I've learned enough that this should not cause any problems, but as always with any mod, nothing is guaranteed, so backup your saves. Enjoy!
