[RuneScape] Implement a family plan or multi-character slot system

With today’s news that the 12-month membership is jumping to **$131.88**, we have officially hit the point where Jagex’s account model is no longer viable. For nearly two decades, we’ve tolerated paying for membership on a per-character basis because the price was enough to justify having an Ironman, a Main, or a PK alt. But with the yearly rate increasing by over 30% (and essentially doubling over the last few years), the "Jagex Account" needs to actually mean something. Let's look at the "competition" in 2026: * **World of Warcraft:** \~$15/month for **60+ characters** (Retail + Classic). * **FFXIV:** \~$13/month for **8-40 characters** (depending on the sub). * **Old School RuneScape:** \~$11/month (yearly) for **ONE** character. I was looking forward to the 2026 roadmap, but asking us to fork over $130+ for a single slot in a game where having an alt is the norm is a massive ask. If I want to play my Main and my Ironman at the same time, I’m now looking at **$260+ a year.** Jagex, you’ve consolidated our logins into Jagex Accounts. It is time to modernize the subscription. If the price is going up to reflect "modern MMO standards," the benefits need to match. We need a "Family Plan" or a multi-character slot system. Charging $130/year for one character in 2026 isn't "inflation" it’s a relic of 2004 that the player base shouldn't have to carry anymore.
