I'm just going to come out and say that I really don't like this weapon. Not because I hate fighting it, but because I hate seeing someone with it on my team. I mostly have this problem in Ranked when I'm trying to get better at the game, and it's with all Splooshes. For some reason, everyone and their mother thinks that Splooshes are good (when they really aren't), these people use them, they end up going 2-11 or something, and we end up losing because we literally had a guy on our team, who was useless for the whole game because a) his weapon can't paint, and b) he couldn't use the Sploosh's "amazing circle-strafing and unparalleled time to kill" to get kills, and thus he died in basically all of his engagements.
I know that I seem mad salty right now and that I'm being that guy who blames his team for all of his losses. Well, that's because in part, most of that is true. And that's just the problem: the fact that people hype up the Sploosh to be all that, when in reality, it really isn't. I shouldn't have to blame a guy on my team for contributing absolutely nothing to the team because he/she used Sploosh of all weapons.
But seriously, Sploosh really doesn't do anything better than any other weapon like it.
So what if it can kill at close range st the speed of light? Tentatek/Wasabi can do this too, just with more flexibility because unlike Sploosh, they can play at a range away from people as well. If, hypothetically, I can Rush someone down with both a Sploosh and a Tentatek, I'm going to get the same result; a kill. If I get right up to my opponent with both weapons, I'm only going to kill a little bit faster with a Sploosh than with a Tentatek. However, assuming I'm a good Tentatek main who's, perhaps, getting in an E-Liter's face, I'm going to get the kill, he's not going to be able to do anything about it, and I'll still be alive. I don't need to use Sploosh to get that very same kill, just faster. It's not necessary.
Then it's not even good at painting. It shoots ink a couple of feet away from... well, it's feet. It has a wide spread, but who cares? If I have a wide spread, but too low a range for that spread to cover a lot of Turf in front of me, I'm not actually turfing at all. I think people have this weird conception that building special fast = painting well. Which it doesn't (and Sploosh doesn't even build special all that fast).
THEN the biggest flaw of the weapon: it's mobility for something with its range. Many people say "oh, use a bunch of Run/Swim Speed and Sploosh will go crazy fast, it can strafe quickly, it can do this move..." etcetera etcetera. It doesn't even run faster than Splattershot. Yep. Those two, drastically different weapons, have the exact same mobility while moving. It also runs at the same speed as Jr., Aerospray, and Splash-o-matic. So it doesn't even outrun N-Zaps. What, in any capacity, restricts these weapons from doing these strafing and mobility techs just as fast as (if not faster than) Sploosh can?
You can see that I talked about the Splooshes as a whole and not just the 7. Because seriously, they all have the same problem. I mean, you can argue that Sploosh 7 has a kit of range options, but it doesn't make it any more useful than the weapons that do exactly what it can do (and more), but better. It makes it the best Sploosh, but that's about it. It's still a bottom tier weapon in my eyes and I really think people need to stop trying to justify why it's good or worth using, because it really isn't (not even the 7 is worth it).
And before you say people don't think this, I stumbled upon a Reddit comment that listed Sploosh 7 as one of the best shooters in the game. Something to think about there.
