I`m getting some small hype for Lissandra. She`s been due for a long time now, glad to see she`s porbably going to end up being AP, I love me some mages. It also goes with how each of the princesses play differently from each other, Ashe is physical range, Sejuani is physical melee and Lissandra is ranged magic.
You are trying to understand madness with logic. This is not unlike searching for darkness with a torch.
