Still no hard numbers on Summon Aerie

So there's still no explicit cooldown or travel time on Summon Aerie, only damage numbers. The showcase video seems like it takes maybe 3-4 seconds for Aerie to return to you, and gives no indication if this is dependent on travel time or if travel time/CD scales with level.

Arcane comet and summon Aerie are nearly identical, but we're left deciding between them based on what feels best because without hard numbers on Aerie we can't mathematically come to a conclusion regarding which is best. Assuming Aerie is only 3-4 seconds at all levels, it could radically eclipse comet in strength until the mid-late game as a poke tool. It's looking like Aerie is going to be better than comet in the vast majority of situations even on champs without shields.
