Why does Lee Sin do magic damage with E but scale with AD
Tempest / Cripple
Cost: 50 Energy / 30 Energy Range: 425 Tempest: Lee Sin smashes the ground, sending out a shockwave that deals 60/95/130/165/200 (+100% bonus Attack Damage) magic damage and reveals enemies hit for 4 seconds. If Tempest hits an enemy, Lee Sin can cast Cripple for the next 3 seconds. Cripple: Lee Sin cripples nearby enemies revealed by Tempest for 4 seconds, slowing their Movement Speed by 20/30/40/50/60%. Movement Speed recovers gradually over the duration.
AD scaling magic damage? Why can't it just be scales with AP and deals magic (since it already reveals stealthed characters anyways) or scales with AD and deals physical damage.
