Also remember that shields are already stronger than heals on average, and prevented damage is no less valuable than healed damage. You would absolutely still have reason to level up your shield skills.
11.5 +3.4 armor per level
meaning she gets 72.7 base armor
plus armor yellow runes since everyone playing bot lane should use those
which is 85.7 armor
plus 6 armor from defense masteries
means 91.7 armor at lv 18
91.7 armor = 48% damage mitigation
ur math is wrong bro
