I said that corki has better waveclear than akali... I would say that his waveclear is about equal to malz but not sure
non-mages are still the most popular champions in mid lane. if we account for all divisions, they are 7 of the top 10, gold plus: 6 / 10 , diamond+ : 6/10
What evidence do you have for these champions being a problem? Wave clear is a mage's job along with crowd control and area of effect damage
funny thing, assassins counter all but like 2 mages: anivia and malzahar, who are designed to have strengths against them but weaknesses against other classes or in general
Galio is not a mage, he is a tank with high AP ratios. He can be played in a mage-like fashion, particularly battle-mage, but he is a tank
aurelion sol is a very rare pick with his only strengths being: wave-clear and poke damage, one of which is out of favor now...
