tbh there's not a lot of other weapons I would play at all now that I've rediscovered s-blast after the buff. but here are some of my 4 star weapons and why I stopped playing them (and/or tried and failed to play them again)
I would play ballpoint, but the accuracy nerf feels terrible. the long range mode might as well be a 5 shot.
I would play liter, but I don't want to be forced to stay back.
I would play rapid deco. And I still do, sometimes. But the lack of options at short range means it can't be as aggressive as I'd like.
I would play pencil, but I like the killing potential more than cooler spam. (I guess I could try 5B?)
I would play naut, but my tracking aim is terrible now that I'm playing blasters again.
I would play squiffer, but it has no good ways to get in range, except zipcaster which is hard.
