Single target spells drawing minion aggro
That is absolutely stupid. It was made for the top lane. But literally every single mage in the mid lane that has a single target spell just got hurt against melee champions. Champions like Fizz, Zed, Talon, Kass. Who can all one shot you once they hit 6 now get to be safer in mid lane.
What are you going to do about these champions that were designed around being melee. Aka Kata, Akali, Fizz, Kass, etc. They only get buffed in this regard while still being insane enough blow you up after they hit 6.
