Does Sejuani feel really weak to anyone else?
I completely love the concept of
! Who wouldn't love a booty kickin' chick riding a giant boar that rains freezy doom upon the enemy team?! Well Poro in my case, lol. But my lord does she feel sooo weak in both the jungle and in lane. I understand trying to balance out everyone, but the current meta of items kinda leaves Sejuani out in the cold. (couldn't skip that pun.) I was struggling pretty hard just trying to clear the jungle camps, and even ganking feels like a bit of a chore. At best i felt like a glorified support going off meta to jungle.
I stacked hp gear for the W boost, but by the time it gets substantial, it's canceled out by the fact everyone else is buffed up too. If you try building towards buffing the damage of you Q/E/R you hemorrhage damage into your W. It's kind of like holding a double edge blade. No matter which way you try, you're gonna get cut. Is there something i'm missing, or is she rather underpowered atm? Or can someone steer me to a good guide? 
have fun dealing true damage (to everyone with less than 50 MR)
and still have ample health to gank. Her damage really scales exponentially off her health so she actually doesn't need any kind of AP runes and I usually always take
towards the end. But anyways I think Sej does MODERATE amount of damage. I mean she has so much cc and I think if she dealt extra damage, she could reach the point that people can start building and using her like an AP burst champ. I've actually seen her burst but only if people lucked out on risking full AP (what more if she did more damage right?) Honestly I would prefer keeping her this way than have her buffed and then nerfed into something less than she already was. For jungle, my brother made a mastery page with some Attack speed in it. I think you should try that if you havent yet.
