New item for AP Mids

Name: Deathfire Grasp Cost: 3200 gold +120 Ability Power Unique Active: Deals 100+(.3)AP Magic Damage to target champion and amplifies your magic damageto the target by 20%

Seriously how is Deathfire increasing mage burst by 20% more oppressive than the new shiv (increasing their burst AND sustained damage) with Yasuo/Tryndamere, the new crit mastery, etc... I thought that AD midlaner meta was a fluke that Riot was going to limit to the traditional NICHE picks of Zed, Yasuo, Talon. Preseason proved me wrong.
