I think most use of archers in a seige or battle wound include more of a rain of arrows, as opposed to all the archers picking single targets from relativily close range. A better nerf for archers, in battle anyways, would be too have archer squads fire in waves, with less acuretsy and a wider range of fire. Still useful to kill attacking massed goblins but not so op. Maby a slightly slower rate of fire. Something different for hunters and lone sharpshooters would be needed. That would take a lot more work though, and this is stil a good quick fix.
Sorry for spelling im useing a phone.
