If frost queen active is targeting player 1 and player 2. Player 3 can intercept it and block it from its target (like caitlyns ult). Since this is how it works, it is a projectile so yasuos windwall should be able to block it.
Units are not blocked by the wall (as much as you might want to classify a flying champion/minion as a projectile), and they are ghosts of something, so you could technically say they are units, and is probably how they are coded :3
Or they might change it. Who knows?
Ghosts aren't projectiles, they're animals, too! Ghost rights!
