Avatar 3.0 is a great addition to VRChat and it has opened up more creativity with the use of multiple features and such. It's extremely powerful and we could have even better avatars with it.
But with it, it became even more complicated to casuals like me and we cannot always ask people what's this or that. Sometimes, we need a really good example avatar loaded up with examples states and expressions so that we can be inspired and learn from the avatar and apply to our own.
Even if it's just a Nikkei or a dummy would be fine. Just enough to make us check out the avatar and see what it has to offer. Download links should be in the FAQ.
