There is a bit of a difference... their justification of nerfing the MR runes was because pure MR made the AP runes worthless and offered much more tankiness than the AP runes could offer offensive capabilities.

They didn't nerf the MR runes to nerf mid lane tankiness, they nerfed the runes so other runes could become more viable.
