Yasuo mains' logic according to their feedbacks in his nerfs/counter-arguments

• Mordekaiser is the fastest champion in League of Legend.
• Karthus's AA is the best tool in cs-ing minions.
• Magic damage among AD damage dealer is the most superior damage type, such as Pantheon's W & Jinx's E, and by nerfing these, they will have a hard time cs-ing.
• Galio has a higher winrate than Yasuo does, so Galio should be nerfed.
• Mana-less champions will have a harder time saving their abilities more than mana-resourced champions.

Explanation to these points are given in Big Lincoln's comment.
