As an example: When i read about a female High Elf who is just 22yrs old, I'd consider her to be a little child in the eyes of her people and propably by her cultures standard.
When looking up the different races, i found to tables: One "canon" (which has propably been retconned several times) and the "non-canon" one from the WarCraft RPG.
Brings me to the Question: Which one would we or you consider to be the "right" one?

The "canon" one has most races entering adulthood similar to humans.

The one from the RPG has very different ones though, which feels more "authentic" to me.

As an example the Night Elves. I read that Night Elfs wouldn't get their Tattoos until their rite of passage, entering adulthood. Without marks they're seen as children (or they deem themselves not worthy of their facial marks yet).
What are your thoughts on this?
