As much as the newest list of Ahri's changes are highly experimental, I think they are silly
It's quite clear Riot has hit a dead road with
's changes that they resort to making drastic changes to a kit that is modern and healthy in League. Instead of making big changes to a champion whose relatively healthy in design, a simple way of making a champion's highs higher and lows lower is to consider a straight buff, and this especially fits in
's case because of her over nerfed W.
You want to make W satisfying? Just go back to her old values
64/104/144/184/224 (+0.64 Ability Power) > 80/130/180/230/280 (+0.8 Ability Power)
Lower W's acquisition range even further, change E to no longer deal damage and take away the % damage amp. Keep R's current buff plans.
Boom, you still establish E as a kiss of death, you retain the set up functionality of the ability and you have now made W a much more satisfying spell to use. I don't see why we can't establish Charm as a kiss of death without its % damage amp.
In the past, both Ahri changes - E %Damage Amp and Q %Move Speed were equally frowned upon. These changes are just moving Ahri back in to a spot where it intended to move away from. Essence Theft is such a healthy passive, not the most interactive passive but certainly better than a mana refund, because it makes no sense thematically for a nine-tailed fox.
If W has too much free power, simply reduce the base and ratio by a little, buff the damage's diminishing returns.
The case in point is, why are we cracking our heads to buff Ahri? We've gone to the point where we are removing a thematic part of her kit, which makes no sense.
