A) Shillelagh isn’t even on the Ranger spell list (no cantrips are), and Rangers will use their DEX for bow or finesse weapon attacks.
B) Of the 61 spells on the Ranger spell list, 14 require a saving throw, 2 require making a spell attack, 1 (Cure Wounds) adds WIS for extra healing, and 1 (Dispel Magic) requires WIS for an ability check if the ongoing spell is above 4th level. That leaves 43 spells where your WIS is irrelevant.
C) None of the above matters, since your original topic of discussion had nothing to do with weapon attacks, spell attacks, spell save DCs, skills, or saving throws. The only thing you mentioned in post #57 was class features keying off an ability score.
A. Anyone can get Shillelagh via guide origin.
B. Druids now have a ranged cantrip. Longbow now require 13 strength
MAD as you want wisdom and con. Ranged attacks got nerfed hard.
C. No comment.
Basically if your build needs a cantrip, level 1 spell or whatever it's easily available.
Opportunity cost though can be argued.
