FFXIV added 24 player hard raids called “chaotic raids” that’s absolutely a nightmare. They have a few 48 player raids that are more midcore content that works well, but 24 is super common and works well for other casual content. But most midcore/hardcore raids are 8 player, and that feels like a good spot.
Had this realization at a brewery and bars two years ago. The music playing there is stuff I grew up with.
