Azir Ultimate
it's only speculation as to if Azir is the Third Brother to Renekton or Nasus, but he obviously shares the same connection/theme as they do
I would have liked Azir to have a similar ultimate where he grows larger, gaining an increase to his maximum health, while having a sandstorm (or maybe summoning an extra soldier) deal damage while converting it to bonus AP (assuming that's what he scales with)
