Why are certain champions nerfed when they become relevant when
other champions aren't even touched when relevant/"op"
ex. 
in the beginning of s5, 
whenever she saw play, 
with cinderhulk, 
with devourer, 
when she was shifting into the meta, 
with DFT, etc...
All are champions that don't have such a high pick rate. However, it seems like when they're finally starting to see some play, they seem to get nerfed repeatedly (especially but I know it's because of the passive)
However, when 
and a lot more are in an OP spot, whether it's because of a new item, mastery, direct buff, etc.... they are ignored and receive love taps at most even when lots of the whiny babies on reddit and the forums complain about how stupid they are. And when their win rate drops and they're in a "meh" spot? They get buffs immediately
I've heard it's because when certain champions are good, they always win, while with others, it's not the case. But what do I know. I actually want to know why it's like this cause it's pretty funny.
THIS IS NOT A QQ THREAD, I ACTUALLY WANT TO KNOW WHY
