For some reason Shyvana was nerfed HARD by all the S3 changes. While Sejuani and others are changed continiously to fit the new situation, she never got mentioned. Not even once since S2 ended.
Why ? She was the jungle queen but now... There is absolutely no reason (besides fun) to actually pick her over Nocturn, Lee, Mundo or other lane or jungle picks.
She was really strong without beeing op in S2, people were scared of her but nobody screamed op.
Now the items changed, the jungle, the enemys changed+ how they interact with the new items and I have to say... she doesnt. She always had kind of a strange kit, but now it is actually more cost efficient to buy CDR and crit on her then ats. Making her somewhat of a jungle adc, without the gold or skills to support it.
