User blog comment:RoznosicielCiast/Why Sejuani is getting reworked?/@comment-4442345-20130214173651

Because she needs it? Her design wasn't good. She doesn't accomplish what Riot wanted her to do well enough. I think they could tweak her by fixing some of her cooldowns (like on her Q, eww.), but she still doesn't have any defensive steriod and she scales with health so that leads to her being focused and killed in fights early-mid, any competent jungler will destroy her in her jungle causing her to not do well if jungling, and she can not peel for her team. If someone gets on your ADC for example, your only way to protect them would be ulting the person. Slows? If the dude jumping on the adc has cc or a slow himself (or is ranged?) gl trying to protect them if your ult is on cooldown.

I think the thing that is more of an issue in the way of reworks is the AP SION REWORK. Wtf is that about? =.='
