I like the idea of changing Jellyhorn arc. I also like the idea of the flare following you, sort of like that cheating axion b**ch grenade, but you actually have to earn it by using heavy. So the rocket wouldn't actually have a blast radius initially, but instead implodes and releases a solar flare that tracks you down, giving burn damage, but when the flare timer runs out, it releases its blast radius like how a star does when it runs out of energy. It could blind someone, but that might be too much.
