Nades on Nades needs to not have a cap in damage. And the individual grenades need to do a little bit more damage.
As it stands:
Explode (for full damage?)
The drop 5 little grenades in an unreliable pattern (even after the buff)
Max of 50% bonus damage to any one target.
Just as a reminder: Grenade damage is 208 at level 2 when you get Napalm
Napalm does 720 damage over 6 seconds, which is 120 per second
This means that:
EVEN ONE TICK OF DAMAGE DOES MORE DAMAGE THAN FRAGS CAN EVER DO
So, to reiterate, my fix (keeping the current mechanic):
This gives a theoretical maximum of 520 damage at level 2, still less than the damage from JUST napalm, but it’s burst so, that’s okay.
My preferred fix would be to rework the talent entirely and make it so that you have two shots instead of one on a single cooldown. (kind of like Whiskey, but without the delay between charges).
