Thought it'd be fun to come up with my predictions/hopes for the new weapon's alt kits.
Custom Explosher - Squid Beakons + Splashdown
I think it's about time we got this kit on a weapon, and what better than a backliner like the Explosher! It'll be in the back ready to support it's frontliner teammates with the patented superjump-splashdown! Beakons work for this aswell especially since you can see if enemys are nearby. I want this kit the most as it's unique and will be uber fun, but it's also probable too as no Slosher has Beakons or Splashdown.
Ballpoint Splatling Nouveau - Squid Beakons + Suction Bomb Rush
Wont be as much synergy with Squid Beakons here, but the Ballpoint is so versatile it can afford not to have an offensive sub. Wouldn't mind Inkmine either but that's already on the Custom Hydra. Similarly, a varient of Bomb Rush is the only special Splatlings don't have. This kit should be good for maintaining constant pressure with Beakons letting your team get in faster and Suction Rush for map control.
Bloblobber Deco - Inkmine + Stingray/Inkjet
I'd prefer Inkmine on Slosher or Sloshing Machine as they're mid-range frontliners where mines shine the most, but since that's not possible unless we get Sheldon's picks, I'll hope for it here. Even the 20 dmg from tagging reduces the number of hits Bloblobber needs to splat so there's definitely good synergy. Couldn't decide between Stingray or Inkjet, but both aid the weapon's weakness to highground/rival backliners. Too bad the weapon will probably be nerfed into the ground. =/
Nautilus # - Curling Bomb + Burst Bomb Rush
Curling Bomb should be pretty self explanatory on a weapon that can hold charge for an extended period of time. Also allows the Nautilus to instantly move instead of having to charge first. As for the special, another variety of Bomb Rush since Splatlings lack them. Burst bombs fit the weapon's fast aggressive nature methinks.
Now watch me get every single kit completely wrong!
