CB never worked against hard bosses in ubers, you only feel difference during leveling, act bosses, superuniques.
Leveling definitely isn't the best, especially if alternative is something like treewarden.
Very weak start in a1-a2, then gets better, but still nothing special, Your skills are mostly aoe and not multihitting enough. If you make lot of uniques, its gonna be smooth, but thats being carried by gear.
For endgame you can definitely make very good farming version, there is good selection of very good bows, including mr painless which is its own realm of power.
Homing nova shot I havn't tried, but unless something is wrong with that skill (for example really short range or weird target selection), it should be very good single target:
Full fire conversion makes it extra premium, possible to scale it further than physical skill.
