Archers are fine now.It takes high level to use the better bows accurately and it requires all their wpf.They need to wear light armor to hit anything really and they are shooting slow due to the new animation.Bow damage is cut, so you cant really kill Plate-users(Hence Mail) alone.
Archers are more of a support role in cRPG now than the Snipers they were before, which is very good.
