@TomAbernathy or @RiotOpeli, Is this really the level of lore we're to expect from now on?

From the recently updated PBE:

"Cassiopeia is a terrifying creature - half woman, half snake - whose slightest glance brings death. The youngest daughter of one of Noxus' most influential families, she was once a beautiful and cunning temptress capable of manipulating the hardest heart. Transformed by the venom of an ancient Shuriman tomb guardian, she continues to serve Noxian interests as she always has, just in a more... visceral way."

Is this a placeholder, like many are suggesting, or is this the actual lore that will be coming out for these champions?

Then, specifically speaking about Cass, does this new lore mean that, instead of being Katarina's younger and less knife happy sister, Cass now belongs to some unknown family? Also, why get rid of the Freljord curse? Does this mean that when Sivir met Cass (in Sivir's lore), Cass was human and the opening of that crypt led to Cass's curse instead of a sacred oath to keep a secret?

Please don't do what the Narrative team has been doing and ignore the questions. Please, provide something of an answer at least this one time.
