I personally love the new system 99%. In A20 I used perks for survival skills and heck, I was making motorcycles earlier in the game than if I had specced into the skill using perks because I found the blueprints. I always used BPs for crafting and perks for survival skills.
The 1% I dislike is the new water/"you will die if not lucky" side. I played with two friends and we never found the book to skill us up ONE TIME so we could make a dew collector. We all wound up having no stamina and had to start over. This time we found the skill book on day one and had the dukes to buy a filter too! Basically, if your RNG sucks, you get to start over repeatedly until somebody finds a skill book that allows you to build a dew collector. Only complaint from me and my group so far, we love the rest!
