And if you don't have a router capable of spoofing HomePass, you will never be able to reach that level. If you need external equipment to cheat the system with, that means the system is broken. That's exactly the sort of unfair playing field I was talking about, exactly what I don't want Splatoon to become.
Pretty sure it works on any router you can rename. You literally just rename it "Best Buy 7654" or something and your 3DS picks it up. Actually, I've never seen a case where it wouldn't work outside of incompetence. And even then, everybody has a 3DS. Borrow a friend's, buy a used one, upgrade and keep your old one... It's just not a big deal in the KIU community, especially when there's the default fusion to use. Many of our best use it instead because you don't need to grind for hearts or wait six hours for another Streetpass.
My point is that it's inherently uncompetitive to ignore parts of the game, intended or not. More often then not you're removing depth and arbitrarily altering the balance without a significant advantage. For example, Ink Resistance. Splattershots cover the shootie's feet when shot. Other Splattershots can return fire, and Rollers keep on rollin'. Chargers? They turn over and die. But with Ink Resistance they can escape. It's huge for all three classes, but Chargers benefit the most. It's evident that the game is balanced around these skills, and when optimal gear starts appearing players just steal it from each other. Starting from a new file, you only need to get to level four to start ordering equipment, and there's a one-in-four chance of getting the equipment copied over exactly. That costs 50,000 to buy, which could be a pain, but assuming you don't buy anything else you could get that much in a day of playing. Bad RNG from Spyke could make it take three weeks at most, and even then you're probably not going to be at a decent competitive level at that point. It, like many other parts of the game, is designed to be a community effort.
