Archery? Does it get better?

[Ivory]

So, I've been trying to figure out the secrets with archery!!!

Now, from the very beginning it has been reported that dex helped with the damage bows do. But from my experience, that doesn't seem to be happening (i'm at 219 dex unbuffed). Instead it is just more attack rating.

I also read that bows don't get damage bonus like weapons do.

Basically, will a trueshot bow (20 damage) always be hitting for about 20-22? From level 1 to level 50? (Using basic arrows)
