AOE 3 DE Bow & Crossbow graphic and audio issue

I don’t know if anyone else has the same feeling: the arrow of bow and crossbow units are kind of invisible and hard to tell if they have done the shot. Compare to gunpowder units, you can clearly hear the gun shooting noise and visible trajectory.

In the early game, it is not a very significant problem because the mass of units is small and no other “noise”, once heading to the mid-late game, the mass of units getting bigger and the type of noises getting more and more complex (gun shooting, cannon shooting, roaring etc.), kitting opponent by using arrow based units become a nightmare.

If people have the same problem, how can we let the devs know about this issue?
