Hey there!
My level is 30, but I didn't play ranked because I'm simply not ready. I play ganking junglers a lot (e.g 
, 
). and I'm looking for a new jungler can initiate/peel with CC. After great buffs, I started to look at 
Is worth buying(She looks so much fun) or is there way better and funnier champions?
If your question is:
Is Sejuani Jungle / Tank fun?
Yes
Will she carry me in ranked?
Just like any other champion, no.
just wait until the new champ out,she will become 4800 IP .
I have been playing since season 2 and I love her. I started playing tanks (Back when Tanks were a real thing...LOL) And she was one of my first jungles. She has so much CC, she is tanky as hell Still to this day.... I went 3/2/15 with her last night running her as a pure tank that came out of jungle, CC'd you, and let the laner kill you, and when we transitioned into team fights I would just stand there with my 
and aoe...And soak up dmg. It was thing of beauty. I would highly suggest her.
Sej is fun to play because she has a load of mobility and CC, and has decent base damage. Also try Amumu and Malphite, overall they're very similar champions.
Only if you can even get past early game with her. Her first clears are garbage so if you ever get counter jungled, you are screwed.
Sejuani has always had a rough go in the jungle, this new jungle is no exception, but not impossible. Haven't tried her since the most recent changes, but in the past I played Q max. Probably go W now. Use your W to reset auto attack, you squeeze out a little more damage doing that. She works well with semi-offensive tank items and CDR, but keep in mind, she's a very moderate generalist. She has no sustain, less CC then Naut, less damage then Cho, less mobility then Zac, and her passive is her only defensive aspect. She does have good aspects of course. Mobility, an AA reset, lots of AoE damage, hard and soft CC, game changing ult, etc.
You really want to maximize your AoE. Get right in the thick of things, keep your W up whenever possible, Q into multiple targets, ult into multiple targets, E after applying Frost to multiple targets, buy items like Sunfire Cape and Abyssal for offensive purposes, and Locket and FH for defensive auras. IBG is a completely viable alternative that will easily proc off her W, but unless you go Magus this will only leave you at 30% CDR. Honestly, Trailblazer + Magus might better then any current Juggernaut combination right now.
Champs like Sejuani win games. They don't necessarily carry games-- and that's a hard distinction for some people to make. They are, however, very rewarding champs.
Sej can't one shot the ADC and she is rather shit to meph early game, that being said, get to end game, and enjoy being Amumu pretty much.
Thank you for your comments! My last question here:
When will her price get reduced? Next week?
Just for the poro rider skin I would say yes.
adds new option
