Please don’t be a warlock, you assume nova bomb is good but its garbage. Thundercrash should deal the same damage as nova bomb, radius should be the same as nova bomb and thats it. Before anyone tries to be slick and say it needs to be better because it puts you at risk let me correct you in saying nova bomb is far easier to dodge than thundercrash and at close range your own nova can kill you. I would take thundercrash over bottom tree nova any day, its far more consistent and its deadly when paired with the melee’s mobility to go across the map in a heartbeat. If anyone think its unfair to get shot down in the middle of the super well guess what? Warlocks are sitting ducks too and easy to kill while in their animation. Both nova bomb and thundercrash are basically the same exact thing, one is simply the opposite in terms of animations and where they are most viable.
Oooor... maybe just buff both of them? I'm sure OP only referenced Nova bomb because it's the closest analogue super to Tcrash, not that Nova is some vastly OP thing that Warlocks have.
