i use the dual squelcher (long-ranged, splat bombs, echolocator) and these are the three mains i have right now:
-gas mask (main ability: tenacity)
-varsity jacket (main ability: damage up) OR zekko hoodie (main ability: ninja squid)
-crazy arrows (main ability: stealth super jump)
does anyone have any suggestions for good dual squelcher abilities/gear? or, does anyone think i should change any of the pieces i use right now?
It depends only on your playstyle, and what you use most out of your kit. However, for a general set, I recommend Comeback, Cold Blooded, and Ink Resistance Up, with any combination of Run Speed Up, Swim Speed Up, and Bomb Range Up. This combination should be tailored to what playstyle you have, unless you have some sort of general playstyle, in which case, having all of them would be very beneficial.
Tenacity is only good if you can stay alive for long periods of time in a match, and if your teammates are being splatted frequently. Comeback is more suited if you often get splatted, which is why I recommend it. Cold Blooded becomes more noticeably viable in Ranked Battles. Ink Resistance Up benefits your mobility while in enemy turf, as well as taking significantly less damage, etc.
The biggest problem in Ninja Squid is avoiding enemy turf. Quite often in Ranked Battles, especially at A and up, your opponents will start covering turf to determine where you are, and if you get hit, you will become a very easy target. Evading becomes more difficult as well, and an aggressive playstyle also suffers because of slow movement.
Stealth Jump is very hardly used, due to the long delay before jumping. Map presence is especially important in all game modes, and a hidden super jump hardly makes a contribution to your team, unless you jumped to a teammate who just died while spawn camping at the far end of the map. Even then, you are very vulnerable with nearby opponents, and will likely take notice when you jump into their ink. If that happens, you cannot escape because of how delayed super jumping is.
A good set to invest in mid to long term is the Tennis Headband, Black Inky Rider, and Red Hi-Tops. The Tennis Headband has Comeback, and favours Ink Recovery Up. The Black Inky Rider has Bomb Range Up, and favours Run Speed Up. Lastly, the Red Hi-Tops come with Ink Resistance Up, and favour Swim Speed Up.
Once you get A+ and up, when your playstyle becomes more stable, Run Speed Up and Swim Speed Up become very useful, and Bomb Range Up becomes more situational because Splat Bombs become more easier to dodge the more skilled players are.
