Karolina (Dupe) or New Cassandra or New High Evolutionary?

I don't do this a lot but I'm genuinely unsure on this one. I have Karolina at R2 and love her but am of course concerned about a future nerf. I haven't really looked into the other 2 yet. I will do my own research, but it's always nice to get opinions. I play all areas of the game except competitive War. So who would you take.???

Awaken Karolina
New Cassandra
New High Evolutionary

Always go for new
