It doesn't have to do massive amounts of damage, Fury was used as an example of someone with signs showing. For an example of not having signs show, Alphonse charging his defensive ability. Without any energy sensing abilities, it would be hard to tell what he's doing; without it shimmering around him anyway. In most cases though, people have some sort of visual for it.

Ranged weapons have a big advantage over most people, especially if they are close up fighters. Range can keep them back, and many end up with close range abilities anyway. I don't think ranged characters are bad, they just get played on the super difficulty level, because most don't wanna say their shot was off because of atmospheric conditions, hence 'Super Accuracy!'
