Pretty much what the title says. Outside laning phase there is no way I, as a caster, could compete with AD champions for minion gold unless I'm willing to either blow two or more spells. It's bad enough casters have heaps harder time last hitting after the bonus minion damage removal, but now I will get less gold for more effort trying to farm up. Not many casters can clear back line minions with one spell anyways, not until well into late game. Brand or Lux for example. Now wave clear, which is primarily why one would pick sub-champs instead of OP all in flashy assassins, is now even less rewarding. I would like to see that change to backline minions reverted, otherwise I see no big benefit in picking waveclear champs, who according not only to me but their pick and win rates, are less potent in the current state of the game.
