Coming back here to update some of my thoughts, specifically on Fizzy and Booyah.
The Fizzy nerf is much more significant than I thought it would be. The 2nd and 3rd explosion are especially close to each other.
This is still an overall good change for the sub, nerfing its painting capability by making it detonate closer without changing the trail or size of the explosions.
The compensation buff to the uncharged paint trail is also nice but I don't think it does much for vMachine. Other weapons like Luna and Tri-Slosher will have an easier time moving in with it though so that's good.
Unfortunately, this also hurts nTri's Cooler output which was already pretty low. The next patch needs to lower the pfs on nTri to 190p but I doubt the devs will do it considering how common it used to be in Turf War tournaments.
Booyah Bomb changes seem pretty good right now. I've been getting more kills with it than I usually do but that's likely to change once everyone has adjusted to the radius size increase.
I haven't been able to tell how fast my Booyah's are charging but I'll be looking back on my replays to check.
Unfortunately, I also haven't had the chance to fight a Bubble weapon to test out the damage buff but I'll edit this post once I do.
