Darius is not a tank. Merely having to build tank doesn't make you one. Otherwise you might as well call Olaf or Volibear tanks.

Elise's risque appearance makes sense given her background. But back on topic, Sejuani is only getting a remodel over someone like Tryndamere and Ashe because her upcoming rework means less work in the long run (synchronization between the different departments and stuff).
