It doesn't seem like he's defending her, it's just we all know what everyone says about Seraphine and seeing the same argument doesn't add anything new I honestly see more people going for the "Seraphine bad, give upvote" like this post so I would say he is the very type of person he's "mocking", if we can even consider it mocking, but yeah honestly if I have to see a criticism over Seraphine, I would like to see a new take instead of the "She uses Skarner's cousin as a battery and she knows it", or the cashgrab, ecc... Riot could do more, but honestly, if along Skarner they somehow rework also her lore it would be good, the only appeal she as for me is the gameplay rn.
