While I love things that are more bite-sized for patch notes and "here's where this unlocks", other content creators will just make a graphic, or reddit will have threads of all the important unlocks.

While it may not be necessary, most people don't want to have to do too much work to find what they want, just that they want the info immediately. Having a graphic you can skim quicker than the patch notes or a reddit thread with a bullet point list works better.

Meoni is great for other things like showing off mounts/glam/visuals, but personally I wouldn't go looking for a video for unlocks unless it's a visual walkthrough of something - needed one of those for FFXI a month or so ago because I kept getting lost trying to get to where I needed to be or looking for a spot on the ground for something (no graphical alerts to say HEY, RIGHT HERE DUMMY and every single ??? can be for anything, not just what you're actually looking for.)
