Questing, Combat, and overall Stats

With there be no "dump stat" and most offer a general postive to everything doesn't that remove the value of every stat?

Does that mean that the combat is more item based with who has the better stuff wins?

That along with no xp for combat means all of combat is disincentived because resting costs money(having to buy supplies).

I know this post may seem a little harsh but I want to discuss the gameplay mechanics of how questing, combat, and stats is going to work.
