this.
Every Ionian but Karma get insane mobility and "outplay" potential. People get mad when they get killed and doesn't want to accept the fact that their opponent migt be better than they are, nor they are "honorable opponent". I myself always give out that honor for anyone who was against me top or mid that won the lane without jungler help.
Seriously though, every Noxian is also a powerful pick against Ionian.
Darius will wreck any top laner that is an all in melee and let him reach in range
Vladimir will destroy any sustain tank that have no all in capability such as Malphite
Leblanc is Leblanc, nothing much to say here
Swain is great in extended fight
Draven is Draaaaaaaaaven
