Cassiopeia's role

Right now Cassiopeia is a single target dps late game scaling hyper carry mage. Also, right now she is not at her best imo, both thematically, gameplay and popularity wise. I believe Cassiopeia would be more popular and more appealing if she was moved to a more assassin type of roll. I believe it fits her theme better; when I think about snakes, deathly is the word that comes to my mind, snakes are specialized hunters and assasins, just one bite is all it takes, just one embrace of their body will do the job. Also, I think Cassiopeia's personality if more close to a calculating assassin niche. In "Descent to the tomb" the Shurima event video, when Cassiopeia betrayed Sivir she acted like an opportunistic assasin, stabbing Sivir in the back. That's just how I picture , a manipulative, calculating badass assassin bitch. I know her current direction might be far away from this theme that I'm proposing, but it may be something to be taken into consideration.

This is just my thought as a Cassiopeia main and fan.
