Hmm, I guess the 7 meters of increased range is a benefit. But why would you use scout for an enemy above 10 meters away? Assault can do a heavy amount of damage, and if the enemy gets too close, you can always use melee to finish them off.
Unless you are really good with scout, and have used it instead of other classes, then yeah, it would make sense. Especially if you are a pro at flag grabbing.
