No reason other than PPs. And flavor...
Back to the original point, unless you want to pursue the Battlefield Archer or a Beast Stalker Paragon Paths (or any future Paragon Paths that require the Archer Fighting Style) there really is no reason to take the Archer Fighting Style build. Even if you have 12 Strength and never intend to melee in your life, you should go with Two Weapon Fighting style. Toughness is generally much better than Defensive Mobility, and you also get a unique ability(as useless as it will be to you) that you can't get anywhere else.
I don't have Martial Power, but I'm thinking the Beastlord Ranger style is also superior to Archer Fighting Style, as you get a cool pet and lose a mediocre feat. I think I've heard you also give up Prime Shot, too, but as an archer, you don't exactly want to be the closest PC to your enemies all that often.
As it is, Archer Fighting Style is just weaker than the other options, even for dedicated archers.
Later!
