PtA, LT, Aery, and Comet need some rearranging
Step One: Aery no longer deals damage. Instead, it causes the target to be vulnerable for some amount of time. Exact level of damage amp to be determined.
Step Two: Comet now uses Aery's current targeting paradigm. Damage an enemy champ with anything? Comet goes flying out and clocks them in the face, orbits them for a few seconds, then returns to you. Repeated instances of damage increases the Comet's return velocity. This is the poke Keystone. Electrocute is the burst option.
Step Three: Press the Attack loses its damage amp. That's Aery's job. Instead, it keeps the three-hit proc which now triggers every third hit. Maybe it's flat. Maybe it's ramping. Maybe it is based on the target's %Missing HP. Either way, it does a specific thing rather than all the things.
Step Four: Lethal Tempo now triggers against EPIC monsters and towers in addition to champions. This gives it a clear niche distinct from Press the Attack as the objective-securing option.
BONUS STEP! Add a new Keystone to either Resolve or Sorcery that grants stacking AD/AP like Fervor of old. Quite a few champions desperately need it.
