I feel like Aery is so much better than Arcane Vomit
While Aery does less damage per hit on a lower ratio, I feel like it is completely better than arcane comet:
- Guaranteed to hit, so more champs can use it
- Lower base cool down
- You get a little buddy (as soon as riot fixes the FX bug)
- Works on both damage champions, supports, and even rivens.
- The damage does add up over time to be a non-trival amount
I mean compared to how lackluster Arcane Comet feels to use, Aery just seems more fun in game. Subjectively I feel like it's the better of the two keystones.
