I still think Torpedo's ring of explosive pellets should be reworked into a unique sub. I'm thinking a 45% cost contact explosion sub with a small 35 damage radius and a bunch of 12.5 damage pellets. Primarily for chip damage, secondarily for cheap paint to help options that need it most, like blasters or rollers. Serves as a nerf to Torpedo's threat level in the process.
Fizzy Bomb should have its damage reduced from 50 direct/35 indirect to 45 direct/30 indirect, reducing its chip damage power. Then its ink cost should be tied to its level of charge; 55% for no charge, 60% for partial charge, and 65% for full charge.
