User blog comment:YourPrivateNightmare/Sejuani, the story, the problem, and the possible solution/@comment-15244341-20141105220626

Funny stuff, but reading the season objectives Sejuani is directly mentioned as a champion with issues by Riot.

One thing you didn't mention that I think needs to be pointed is that Sejuani, for not having a good defensive steroid, has decidedly mediocre stats. Her health is not that awesome for a tank, neither is her base armor (understandable, I guess) or basically any defensive stat. So it's not like Mao, that makes up for his lack or MR/Level with insane stats (like armor). Or Shen, that gets a 200 health shield every few seconds.

I am also on the fence about this, but I believe Riot have not touched Sej defensively so much because of Oppression. For people that don't want to look it up, it gives a 3% damage reduction from enemies that have impaired movement. They might have thought that this could be a bit too much considering how Sejuani's kit works. That said, she might get something good before the new season with the stat adjustment.

Also, while I don't care much about her splash art, I'd say she looks pretty damn cool right now. Even if I did like her before, I like how she looks right now.

In agreement with everything else. I'd say they might have overtuned her when launching the rework and then nerfed her a bit too hard.
