Why do some of these require two abilities? Monk for example seems to require Strength and Dexterity of 14, even though you can create a Dexterity focused monk on its own. This seems to run counter to at least one of the descriptions...
'Rogue monks are incredibly effective because stances grant some of the best agile finesse attacks...'
Except you need a 14 Strength to use them suddenly? Am I misreading these requirements? The Fighter suffers from the same confusion. And an argument could be made that the Rogue dedication should have a choice of abilities. Barbarian and Champion are less clear as they require a 14 in a secondary ability, not two different primaries you could build the class around. This seems overly punitive toward the martial classes, as all the casters only require their casting ability.
I think the intention for something like the Champion is to make sure the character taking the dedication feat at least has somewhat appropriate stats to the class and isn't just dipping for an ability, like a wizard spending spare feats to pick up lay on hands just to do it.
I think the Monk and Fighter should have the option of the two abilities rather than requiring both at 14, however. The classes are designed so you can focus either Dex or Strength and be fine. Plus, its not like they put the same restriction on rangers or rogues, even though they could also sometimes benefit from having both abilities high.
