Genuine Question For Peni Parker Haters

As a peni main myself, I have to ask you guys why you hate her so much? When I go against her, she can be slightly annoying at best but other than that she's not too much of a problem like the other tanks. It it the people who play her that annoy you or is it her playstyle or something else. Be as honest as you want I just wanna know why.

(Fyi I'm sort of new to the game and I picked it up this summer around late july/early august)
