I cannot fathom in the slightest why it is acceptable for Morgana to have that stun of hers.

Maybe all of you can explain it to me, because I don't get it. Morgana has this root that lasts a ridiculously long time, that costs very little and has high damage. I literally, cannot understand why this is allowed to continue to exist. And don't even give me the whole "all you have to do is side step the skillshot, it moves slowly" bullshit, because I do. But she has Blitzcrank syndrome, where no matter how many times you dodge the skillshot, one slip up and you are literally dead. But at least with Blitzcrank I can flash away before he and his team can completely obliterate me, but with Morgana I cannot. And in the late game, that THREE second root is usually followed by an ultimate that roots you for even longer. It has a two second base root. BASE! I mean... why? And do not even get me started on the Black Shield. I don't even want to talk about that. You can feel free to downvote me because I obviously don't understand how hard it is to play a champion who is basically the support equivalent of a point-and-die adventure game.
