So Aery is too strong right now, right?
or is it just me? I'm not whining about getting destroyed in lane by it ( i mean i did get f*cked by a Aery Panth... the guaranteed damage was real lol), in fact I have absolutely destroyed ADC's in 1v1's as Nami with it (I hear Sona is even worse). So far I have seen anyone with long range poke take it, most mid laners seem to take it, nearly all non-tank supports take it.
Why even bother with Arcane Comet? Its accuracy is too low and its damage is only higher than Summon Aery later in the game, but the damage isn't guaranteed like Summon Aery. Plus if your champ can shield/heal allies, like Lux or Ori, it has the secondary bonus of giving them a shield. I suppose it is better if you have a stun or a heavy slow that will make it more likey to hit. Still for now I'd rather take Aery since it doesn't require aiming and does a lot of early game damage.
