Ray of Redemption/Light Redemption vs. Spectral Light (Luminous)

I've found uses for training with it in some niche areas. The range is enormous, especially the height. I think it can hit all the platforms in the Roids MD, making it super ezmode. It's too slow to be that great though in regular scenarios, and only useful if you intend to OHKO train on things with platforms where you don't miss too much on. Spectral Light is the lesser of two evils for training eventually since it gets you out of Sunfire faster and is just plain stronger. If you're strong enough to OHKO everything with Nox Spear without Eclipse, then it doesn't matter. Shine Redemption should have utility when you're in 4th job if you want to heal for some reason, but 4 points is enough.
