The Fighter says "Choose a weapon and/or combat style. Your sub-class is a fluffy job that might USE that weapon and/or combat style."
How does that make any sense? If I'm a Fighter and I want to focus on light armor, light weapons, and perhaps a bit of archery... why do I have to be assigned the JOB of "Scout"?
Because we used to have Fighting Styles that made sense, and the USUAL complaint came about "why can only Fighters do that? why shouldn't my rogue/ranger/paladin/barbarian be able to learn that?", so once again they had to bleed all the fighter's stuff out of the class into being available to everyone.
Although all in all I'm not really against the new idea, but I see your point that we already had backgrounds for knights and other "jobs".
