I remember back in splatoon 1 I would try a weapon and usually by the end of the first battle I either liked it, was neutral on it, or despised it with my whole being (usually when I was absolutely destroyed by the other team). I equipped a brush and yeah I don't think I ever used it again. The snipers also I don't do well with. I can manage them, but it just isn't as fun as shooters.
In splatoon 3 I think I'm going to break that habit and try to give every weapon a fair chance with multiple battles. But yeah I remember that as I would be experimenting with a new weapon in splatoon 1 I'd tell my sis "grrr, I don't like this weapon......arfhgh they got me!.....I really don't like this weapon."
And she'd be like, "calm down, you don't know that yet." And I'd be like, "well, I know I like the splattershot, so I'm just gonna stick with that, so there."
I do want to practice more with the splatana though, looks really cool
