i sincerely doubt they're going to nerf tacticooler itself at all tbh. i think they love that it's this good and don't want it to fall from that spot, it really does make the game super exciting to watch
i'm very much hoping for a nerf to snipewriter's range, the fact that it outranges splatterscope is funny but very very dumb and should not be a thing i think. i don't even really think it should outrange regular splat charger but that's a bit extreme so it's not what i expect. but a pencil range nerf would reduce its paint spam a bit, and give other backlines a better chance at fighting it (something that i feel weighing over me constantly when i play ballpoint, even in solo). 220p would also be nice, it honestly would barely even do anything but it would be good just for the sake of like. symbolically implying that it's slower at getting cooler. because really i think snipewriter should not be the best weapon for farming cooler, it provides such good utility in other areas with its chip damage and reliable painting uptime that i think it could do with a weakness of not actually getting special as often as other options
i hope next patch isn't ALL nerfs though. there's still plenty of things that could do with being buffed more (i'm still holding out for them to just buff H-3 into being overpowered because i don't care that weapon would be so cool to watch if it was good). maybe 16th time's the charm and they'll actually buff reefslider endlag, who knows
