"people always forget AD Kayle's q does just as much damage as AP, not counting penatration. They both have 100% scalings"

Except for the fact that AP is significantly cheaper per point than AD (1600 for 80 AP while you spend 1550 for 45 AD) and only becomes cheaper when you factor in deathcap and the +% AP mastery in the offense tree.
