With the .96 Deco I run usually run two Ink Saver (Sub) primary and that gives me enough ink to drop the wall and fire my weapon twice, which is enough to splat just about anybody. It's still kind of a niche trick because it's slow and easy to escape from, but it expands the uses of the wall quite a lot from team support/escape only to something I can use offensively by myself.
I don't think you need to dedicate a whole set to using the wall necessarily, I notice a big difference after just one Ink Saver (Sub), but I imagine that varies some by weapon.
I don't use Ink Saver (Sub) at all with the .96. Ink Saver (Main) is always useful since it guzzles ink, and while I haven't played with the buckets in a while the standard Slosher and Sloshing Machine both benefit from it. As a bonus, the Studio Headphones are favored to roll Special Duration Up which benefits your Kraken on the .96 and Slosher. The Jungle Hat also gives you Ink Saver (Main) and Ink Saver (Sub) as its preferred subabilities, but with the .96 I find that isn't necessary
and that hat is the opposite of fresh.
I generally prefer Ink Recovery to Ink Saver as it benefits both your weapon and its sub, but with the ink hogs Ink Saver (Main) lets you get in more shots while waiting for the delay that keeps you from recovering ink after throwing a Splash Wall.
I pretty mush need help for an idea of my Slosher Deco build.
Because that stuff needs a ton of ink (especially the Splash Wall) i really have trouble using that pretty well combined because u mostly can only use 1 Shot after using Splash Wall. Thats why i am thinking of an Ink Saver-Build. The question just is: Which way is the best?
It's only either 3 Ink Saver (Main) as primary and 9 Ink Saver (Sub) as Secondary or 3 Ink Saver (Sub) as Primary and 9 Ink Saver (Main) as Secondary. Which way is actually more efficient for Slosher Deco?
I actually run of many times to that problem that i can't splat someone because i run out pretty fast of Ink after using the Splash Wall on a full Ink Tank and i pretty want to fix that out in thatw ay that Main and Sub using less Ink to get more use of Splash Wall for taking down opponents in thight places. Without that i really have a problem really fast.
You're over specializing. Diminishing returns kicks in hard when you stack that much (mainly on the mains) and about the only weapon where people go nuts with stacking one stat that hard is the E-Liter...the other exceptions being the freaks who go nuts with either Defense Up or Run/Swim Speed (especially Splatlings).
If you aren't tied to Ink Resistance Mawcasins will give you Ink Recovery and Ink Saver (Main), otherwise Strapping Reds will give you Ink Resistance and Ink Saver (Main). Studio Headphones give Ink Saver (Main) and Special Duration Up. 1 main and 3 subs is pretty much the sweet spot for getting the most out of your gear.
The shirt is up to you...I'd probably go with Squidstar Waistcoat for Cold Blooded and Swim Speed Up (the latter always helps, and it benefits your Kraken...a lot of players run at least three Swim Speed Up subs from Red Hi-Tops), and an enemy getting the jump on you is really bad with the bucket.
While not optimal, give the general loadout a shot with a test setup of Ink Saver (Main), Swim Speed Up, and either Ink Recovery or Ink Saver (Main) on any three pieces of gear you have and see how it feels.
