Why does shiv get all the hate and very little for seven

Not saying shiv isn’t broken, he is. I don’t like playing broken characters, so I want him nerfed so I can enjoy him again if nothing else. That said, shiv has a negative win rate, seven has a 60% win rate. Shiv is hard to play (people cope and call him easy, then they queue him and mathematically lose most of their games). Seven is arguably the easiest character in the game, certainly the freest in the state he’s in. So, why do yall hate shiv so much more than seven? He gets 10x the hate I feel. Like I said I haven’t been playing shiv as of late, but far more of my games are run by a seven standing in the middle of the fight then pressing unstoppable and 4 than they are a shiv running rampant.
