-so i am wondering , she had 100 hp / level ,now she has 85

-her dmg is only 50 at lvl 1 and barely passing 90 at lvl 18

-armor barely passing 75 at lvl 18 (meanwhile creatures like pyke have 130 armor at lvl 18 for some reason)

-kayle also needs at least 400 ap to get that 20% E back

-mana costs are pretty high also imo

-late game even , using a rotation halves the total mana ..or close to it

-W is 100 mana as is R

-less armor means getting destroyed by renekton/irelia/etc way easier also and getting bullied out more easily

whats ur take on current state of kayle and what is agugustus trying to achieve ?
