Nova bomb only needs a few buffs to make it more competitive in PvP and useful in PvE (but mainly focusing PvP). It’s main problem is that it’s slow, has a very inconsistent blast radius, and doesn’t cover much distance in its flight path.
1. Add Lance to bottom tree Nova bomb. That would make it much better in PvP. Make it travel faster. Have it cover more distance and have less of an arch so that the bomb goes where the user is aiming.
2. Increase the speed of the Cataclysm Nova Bomb a bit. I know it’s supposed to be slow but this is a little too slow. Also increase the aggression of the mini Nova orbs.
3. Significantly increase damage of both Nova Bombs in PvE.
4. Increase blast radius for both Nova bombs.
