So, I use shaders, and holding torches in my off hand is great, but annoying as hell! Constantly placing them everywhere! So, I use a blaze rod, however the light is weak. I'd love a data pack that would give blaze rods a higher light value, close to a torch, so players who use shaders or have dynamic lighting turned on can use them instead of torches, and save them lots of frustration.

I can't imagine that this would be too difficult, and I would do it myself if I knew how xD
