Why nerf heal/shield supports when you can nerf the item?
So, thinking about how heal/shield supports are on the top tier right now got me thinking, "What if it's also Spellthief's Edge?" So I went into practice tool to test it out. A Janna's Zephyr with Spellthief's deals 56 damage to a target dummy, about 86 damage to an adc at level one, but with Doran's Ring her Zephyr deals 51 damage to a target dummy, about 79 damage to an adc level one. The extra 13 damage given from Spellthief's makes supports deal even more damage than what they would do if they were taken mid lane and started with the standard doran's Ring.
