Wrigglestone Needs to Stop
Wrigglestone, Madstone, whatever you want to call it, it needs to go. The combination of Spirit Stone and Madred's Razors promotes the toxic playstyle of AFK farming, where the jungler goes into the jungle for the first 10-20 minutes of the game without ganking or participating in the game at all. Then they suddenly come out of the jungle 2 levels higher than everyone else and several items ahead in their build. This isn't fun to play with or against; if you're playing with someone using Wrigglestone, you're essentially in a 4v5 for the first half of the average game and have to hope the enemy jungler doesn't make your life hell on top of dealing with your lane opponents. If you're fighting against it you're essentially on a timer until the enemy jungler comes out with a massive stat and item advantage and completely destroys whatever lead or advantage you may have cultivated.
Riot has previously made it abundantly clear that they DO NOT approve of AFK farming because it removes participation and interaction; it's for this very reason that they nerfed Wriggle's Lantern and Feral Flare, so that even "carry junglers" who benefit more from farming to the appropriate level are encouraged to make ganks and show themselves on occasion.
Riot has already proven that they can make items mutually exclusive, as they've done with all gold generation items. They've also proven this with their PS5 jungle items, which are not only exclusive but also require a specific summoner spell to purchase. Now while I know there is the option to wait it out until Preseason hits and watch as both the Spirit and Wriggle lines go adios, but Riot has previously proven they aren't opposed to making short-term fixes for the health of the game. I believe this is one of those occasions where a short-term fix is necessary. Wrigglestone needs to be removed for the fact that it promotes a lack of interaction in the game and can lead to a very toxic game for everyone except the Wrigglestone jungler; and even THEY aren't immune, if their strategy bites them in the ass.
Wrigglestone just is not a good thing. It needs to go.
