If you use gear with every ability with defense up, if helps you to be less targeted, and it would be the best thing to use if you are in ranked, and plan to use a charger, or Splatling, also if you use a defense abilities, you might wanna use the three star gear, which does cost more, but you get more abilities, and you don't have to use sea slugs to get more abilities. also if everyone has chargers on the other team, and they shoot you, they can't shoot you right away, you get a second chance to escape.;)
