No ranged classes were ruined. At all. The hits you took were relatively small. SMN is still a ST/Cleaving monster. BLM annihilates every other class in AoE and still has great ST damage.

Bards took the biggest hit. Mostly in utility I suppose, losing RoD's damage reduction. The CD nerf (the only damage nerf, Heavy Shot and Straight Shot 'nerf' are toolkit errors) was figured to be ~7% damage loss. You've still got the best uptime and utility.
