I presented this case a while ago with respect to Guns and Staffs. I believe the conditions are similar for Bow and Daggers.
Bows and Guns are single target weapons, hence the increase in basic attack damage should be a counter to the spread damage provided by Daggers and Staffs. At present the Skill damage from Daggers and Staffs are higher than Bows and Gun.
Not really, though the armor difference should not be very drastic that people don't even consider using a ranged weapon.
My thoughts are based on PVE only, though the lack of armor does affect players in PVP.
The damage output for both weapons should be same. IMO only the stats for survivability (health/armor) should be affected based on range.
