Happy Thursdays! -^^- (Tri-Sloshers)
5Tri-Sloshers: Low range, medium damage, decent accuracy, good ink economy. These are shorter ranged, less powerful, but faster sloshers that throw fans of ink out in three directions, hence the name Tri-Slosher.
Tri-Slosher: Burst Bombs and Ink Armor. Pairing a Burst Bomb with the main weapon can be a very effective way to splat opponents. You can also use Burst Bombs for mobility or use them either defensively or offensively. Use Ink Armor to give support to your team as they push an objective or ink on the front lines. A very good pressuring tool is throwing two Burst Bombs, activating your Ink Armor, the throwing another two Burst Bombs, or three, depending on how much Ink Saver Sub you're using. I only recommend that for the last couple seconds of a match, though, as you'll hardly have any ink leftover to defend yourself. The abilities that I recommend the most are Special Charge Up, as using Ink Armor as much as possible is very helpful. Swim Speed Up, due to the mobility being subpar. And Special Power Up, as Ink Armor is so much better with it.
Tri-Slosher Nouveau: Splatbombs and Ink Storm. Combine the Splatbomb with the main weapon to make splatting opponents easier. You can also use them to flush out enemies that outrange you. Use the Ink Storm to help clear chokepoints and support your team while making a push. The abilities that I recommend the most are Special Charge Up, as the turf coverage isn't exactly the best due to the Tri-Slosher's short range. Ninja Squid, to help with stealthy approaches. Swim Speed Up, to make Ninja Squid faster. Ank Ink Resistance Up, since the lack of Burst Bombs can damper your mobility.
Overall, both kits are very solid and the main weapon, itself is fun to use, every now and then. The vanilla kit can do good in both Turf Wars and Ranked Modes due to it's better turfing capabilities with Burst Bombs than the Nouveau and since it has Ink Armor while the Nouveau I'd say is better for Turf Wars due to it's sub and special.
