No. As I see it, fire bolt grenades are at a level where nerfing the would make them useless. Self res honestly is a huge crutch, and if anyone actually tried to get good with radiant skin, you'd see how good it actually is compared to fireborn. In any case, if bungie nerfs firebolt grenades, it would make the melee the only usable thing in radiance. And melee recharges slower than grenades. If armor is nerfed, it would unbalance the close quarters nature of the super. I suggest that either fireborn or Viking funeral gets a nerf, as Viking funeral is very similar to thorn DOT, it's the most complained about perk. For example, a nerf of 2 damage would reduce the damage dealt with Viking funeral by about 16-20.
