Just checked out the Turf War tier list, and I noticed the sploosh at the bottom of the list again. Do you just hate this gun? It clearly isn't outclassed by the Duel Sqeulcher, as that would require them to be even remotely similar. Duel Sqeulcher is meant to out-range other guns, not out-gun. It's fire rate is awful, it's damage can be pushed to a 5 shot, and it's outranged by the marginally better Jet Sqeulcher. And, hypothetically, let's say I wanted to shame the duel squelcher just a little bit more. If I wanted to do that, I could bring up the Splattershot Pro, which boasts the same range, better damage and only slightly worse fire rate.
Now that I'm done shaming that worthless gun, I can get back to the sploosh. The sploosh has both a higher fire rate and higher damage than the duel squelcher, leaving the only higher stat as range. That's not even hard to do, it has a worse range than the aerosprays. It's range is pitiful, and just because of that, it's outclassed? I hate how people underrate this gun. It's not bad by any means, and I would probably say that it's the best weapon for flanking, and it keeps a great inking potential as well. Horribly biased rant is over.
