@Mysterious Stranger - That all sounds fine for your home campaign. PFS is not resource poor, and there is easy access to wands of CLW, even without spending gold (through spending prestige). I don't think I've had a character yet burn through more than 3 CLW wands over 11 levels, though some of those eventually bought partial wands of cure moderate as well. But even if it goes to 4 or 5, the savings is minor compared to getting an extra feat for your build.
He's also talking about a character that doesn't plan to routinely be the target in combat. So there will be scenarios where he requires minimal healing, or possibly even none. I just played through a scenario at tier 8-9 with a melee character, and because there was a Barbarian next to me with a low AC for most of the scenario, I never got hit. What he should be concerned with is when he suddenly...
He is not talking about getting an extra feat he is talking about taking toughness. There are a lot better choices for feats than toughness. Great Fortitude will give him a +2 on fortitude saves which having only a 12 Con is affecting. Dodge will give him +1 AC and affects touch AC for all those rays and other attacks targeting touch AC. Improve Initiative will increase the chance of him getting to act first and thereby actually being able to use sneak attack. Improved monster lore gives you a bonus of half your level to identify monsters (Very useful for being able to use band).
Toughness is not really all that good of a feat once you are past 1st level. Going from 9 to 12 HP is actually pretty good at first level where one unlucky shot my take you down. After that it quickly loses steam especially since you gain nothing at levels 2-3.
