I mean, they seem to like nerfing jungling items left and right, Warrior,cinderhulk,runic echoes, devourer
Tell me, who honestly kills herald unless its a devourer nowdays?
And call me crazy, but i think Riot hates any female jungler that gets too strong
See how Jax,Yi And Xin only gets small hits or buffs
Meanwhile Sejuani Evelynn and (Dear lord i hope not) Shyvana are useless outside of the jungle?
Sinah2 votesIn most of my games and i think this applies to most people, is that people just forget to kill herald, maybe because we are not used to for a monster to be there that we can kill. And the nerfs, well if they nerf xin just a bit he will become useless (think how no one played him before he got buffed, and then he gets buffed just a bit and he's OP af) same as yi and jax, if they nerf these champions just a bit they will reach trash level, 100%

Bears Dont Care1 votesEvelynn u can give you, but the hate riot has for her is a matter of two things.
Dislike for her mechanics. Unwillingness to change it.
Unless it's lee sin, they will make sure he stays top dog.
Shyvana ate harsh nerfs after a series of buffs, and I say it present tense since the nerfs will go through. Remember pbe is for testing not balancing!
Sejuani got slight buffs. So nay it's not gender stereotype.
Riot is simply blatant about some champ bias because they find it too hard to balance, or too time consuming to change.
Furthermore it is not profitable to do a rework. They don't gain any money due to lower costs of older champs. Better to make sure aurelion sol.
