I'm probably the only one, but...
I'm really appreciating the skin bios that have been added. I actually took the time to go through all of the skins in the game, looking for bios, and some of them (especially the RPG skins) were a hoot. Like, Dark Candy Fiddlesticks drawing his power from holiday anxiety. That's amusing. Or Candy King Ivern has a "gnawing hunger for candy flesh that can never be satisfied". Just the wording of that is funny. I also like the idea of these self-contained pseudo-worlds, like the Winterlands ruled by the Poro King or the story of PROJECT, which is fleshed out through these bios.
These bios are completely unnecessary, but I appreciate the effort.
