One person at a time.
All of the fire rate nerfs stand out as the most obvious cases of overkill. Just as I've done with the two Gals, you can compare every weapon that got a fire rate nerf to other weapons with similar fire rates - and then bear in mind that those weapons are supposed to have other redeeming attributes to make up for being slow, which these nerfed weapons won't even have. And why are we even nerfing low tiers at all? Just to cover up how far the good weapons got dropped so they don't look so bad in comparison?
Which weapons are you comparing these nerfed shooters to? Dualies? Or each other?
Shooters already have a slew of redeeming attributes to make up for lower fire rates than other options. They remain the most mobile class. They remain the best painters. Now, instead of being able to rely on their times to splat, they'll have to actually strafe around and dodge enemy attacks to win fights.
As for the low tiers, Aerospray was given a huge compensatory buff, and both it and Jet Squelcher and handicapped by two bad kits. Splattershot Pro could stand to have its fire rate nerf only be a one frame increase, but it would likely end up badly outclassing the standard Splattershot, and I'm trying to avoid invalidating any shooters by having others be flatly superior. I'm not sure how many other counter-buffs I can give Pro, though. It is a point of issue.
I'm not going to go through the whole list one by one, I don't think it's necessary. I think it should be on OP to justify these changes, because when they've started the thread by admitting they just hate the weapon class and want them all removed from the meta, it's hard for me to take any of this seriously.
You keep repeating this, but it's false. I never said I hate the class. I do consider them overpowered, and I certainly don't want any of them to be top tiers, but I don't want them dead. I actually quite like Pro, .96, and Nova, not to mention the semi-autos.
Don't make assumptions. They tend to falsely justify your mental image of a situation and only ever prove yourself right.
I have already justified most of the nerfs, but I'll add another point: Shooters will survive. Even if my intent were to kill the class, it would be impossible without shattering their identities or halving their fire rates. Their inherent strengths of being able to cleanly switch between swimming and shooting, being able to paint in a wide spread; they will always keep the class afloat. The only thing that's ever made any of them truly weak is their shot spread, which I will never advocate for increasing, or truly garbage kits.
Think about how the weapons would play with the nerfs before writing your next comment. Either your mental perception is wildly different than mine, or you'll see the class operating almost identically, at most forced to use their movement a bit more.
