I see you've committed to being a troll. Funny enough, this happened back with Creator. What happened? People unsubbed because there was nothing to do. Parse runs only last for so long.
Because that is the entire purpose behind a Theme Park MMO. How many people care about Perform, Rival Rings, Crafting, Gathering and PvP in general? You don't see threads screaming PvP be deleted from the game or Perform shouldn't exist. That is content for a very niche audience. In fact, I'd argue PvP has a smaller playerbase than raiders. We're asking for one or two things that cater towards our interest, just as you prefer something like Eureka. Can I do all the dungeons released? Yes. But that isn't enjoyable content for me.
Theme Park MMOs are designed to offer small pieces of the pie for multiple types of players. You don't compare the entirety of everything the game offers against Savage. You compare Savage with say, PvP or Crafters/Gathers. Each makes up a percentage, albeit with some overlay. What you're demanding is raiders get nothing.
What's stopping you from partaking in Savage if you want to see God Kefka? Are pugs difficult? Sure. But I've managed to clear with suspect parties on Warrior, which is not my main. If I can do it, why can't you?
