How does 62 speed on initiation sound swift sparrow and speed wave

As a follow up, Ive done some calculations, assuming both are using the similar setups (Karla with her weapons, swift sparrow, wrath, even spd wave, moonbow, +10 with summoner support while in wrath range, speed+3 s seal), she loses to 3 units that all have Swordbreaker/Wary Fighter or obviously bulky blue, but kills about the rest of the cast. Ayra has the same setup barring her pref weapon, however, due to the cooldown of regnal astra being 2 (for obvious reasons) she gets less kills. She would need to switch to a slaying edge and she matches Karla. Only when the two are at their optimal (IE at the best they can be, switch Swift Sparrow on both for Brazen Atk/Spd) does Ayra pass her by 2 kills, that you shouldn't even try to do ingame (Ayra kills Sully by exact change and Effie as well, while Karla leaves them at 1 hp if Im not mistaken). So in short, unless you need to attack Effie or Sully and you have those specific situations at hand, both are equal in nuking capabilities, with Ayra requiring more investment (that slaying edge) than Karla at first, yet both have the same capabilities in the end. Mathematically speaking, and tactically speaking, theyre pretty equal.
