Blightroar worth to upgrade?

so i heard that the blightroar got nerfed but i’m not sure if i should use it as upgrade material or not.
if yes which item should i upgrade first?
Annihilation or mighty canon?

it aint such a bad wepon, since it has 2 range, it is still usable, in the right combo.
But if you want to use it for 15k powerpoint , then use it on Anihilation.

Hi! I carry these 2 weapons in my phys, but I do upgrade first in annihilation, because they don´t consume energy and are more useful.
