Now, I love the way the various skills of the game help provide a theme for the respective classes. It can also help stimulate Role Play or help a person get a stylistic feel for class. For example, Camouflage, to me, fits perfectly with the Survival spec. Prowling around in a forest, laying down traps before pummeling the prey with exploding bullets, awesome. Collecting various minerals around the world to build mechanical contraptions? The thing that helped define Khajro as a character. (Aside from being a misspelling of a Skyrim character.)
What are some abilities you think help illustrate what certain class are all about? Have any of the professions helped you add some complexity to your characters?
