Surely enough, a month later 14 of the top 21 win rate champions in mid lane are top laners (and 2 are junglers). With how punishing top lane is and how valuable that role quest is, you can't afford to play bruisers/tanks top lane and lose early.
I think if the support item change doesn't get removed, ench mage or mage mage bot will become meta. With the ADC champ farming until quest completes, and the support farming after that.
Ideal comp looks something like:
Marksman top
Normal jg
Tank mid
Mage/Ench adc
Mage sup
