Technically correct. However, at least in my opinion, relying on dodge to evade attacks is a rather questionable strategy to begin with: you will always be one bad roll away from a deep bite wound, if not something worse. Not to mention dodge scales terribly into more difficult fights: start adding more enemies and accumulating some pain, and dodge efficiency drops like a rock. Neither keeping your distance nor using armor has that problem.
As for armor/weapon durability, it’s never been a major issue for me with 4 dex.
Literally never seen a trap I failed to detect on time with per 4. ¯_(ツ)_/¯
Overmap sight radius is handy, but really not game-changing. Use binoculars. Or make an elevated platform with a stepladder and scout from it, that gives you enough scouting even with per of 4.
As for trying to rely on natural vision in the dark, that “works” up until the first couple of predator zombies. Or a single large boomer highlighting you.
Basically, my point is:
everything per and dex govern is either:
- a questionable idea in the first place (night raiding, relying on dodge)
or - can be easily substituted for with basic strategy, tools and equipment
