Maybe if they started adding third kits last season maybe we would have had a chance for every weapon to get a third kit

what do you mean third kit

3rd kits to a weapon, Ex: Splatana Wiper and Splatana Wiper deco. We haven't gotten any 3rd kits in the game for it yet

We had 3rd kits before. Example: Splat Dualies, Enperry Splat Dualies, and Kensa Splat Dualies.
There was also the Hero Weapons, making it 4 kits if the weapon had a Kensa variant and a normal variant, like Splat Charger, Firefin Splat Charger, Kensa Splat Charger, and Hero Charger.
(This is as of Splatoon 2)

Right, but we don''t have a 3rd kit in the game yet-

Wait nevermind, Hero Shot and T-Tek Splattershot exist

Lol. Other then that, no 3rd kits yet (as far as I know cuz I'm super tired and can't think straight)

Don't forget the N-ZAPs from spoon 1
