Re-reading my post I indeed sound like a snob prick so sorry for that lol.
My point was that looking into RDM's kit from StB to ShB, and having mained it along with SMN for these two expansions, I feel StB RDM had a bit more room to push high numbers and I think it's because a good chunk of people I saw in things like dungeons or Eureka had trouble understanding how to optimize RDM's gameplay (which most of the time was linked to Impact, and more broadly to proc management). And I feel ShB ironed out this difference so it makes it even harder for optimal players to push out rewarding high numbers. I'm not saying there was a crazy difference, but that's how I experencied it.

of course it's a fraction in the "everything wrong about RDM today", but I think it's worth mentioning it.
Now the main thing is that competition is hard for the ranged spot, especially when BLM is that far above every single ranged DPS, we know that well enough. I think it would be easier (as a band-aid fix mind) to nerf Enochian from 15% to 10-12% to make any other job buff more impactful (pun).
