[IDEA] (Sub)Classes that are gained and lost by your playstyle

[AyItsJay]

First off: This idea can work WITH or WITHOUT experience, skills, or attributes.
Imagine practicing with a bow for so long you prefer it over a crossbow. You like it because it's quick and practical, along with easy to make. You also like lighter armor because you can still survive bowshots, but it will also allow you to move easily. For some reason, the only food you can find in the forest is berries.
This would give you the following classes and subclasses:
Hunter
You're used to the weight of your light armor- it's like it's not even there.
You know the perfect way to nock an arrow and the perfect way to do the most damage.
+15% damage done with bow to animals and (class)
+#% less sound when (action)

Gatherer
Your diet consists of a lot of berries. Your body has become accustomed to them, and prefers them over other foods.
+15% more food / water gained by berries
+ 20% less food / water gained by other foods

Keep in mind this idea can and somewhat WILL change as comments come by.

Pretty cool idea, I guess.
