When is Miss Fortune being looked at?

I like taking 80% of my HP with one Miss Fortune Q that randomly bounces to whatever fucking thing it feels like. I stand behind the fucking minion wave, and she Q's the melee minion and I think that the Q is gonna go through the melee minion and hit the ranged minion but no the bullshit ability hits me instead of the minion and I lose 80% of my HP with one ability. What kind of fucked up bullshit is this? Some times the bullet hits nothing when there is something nearby, and sometime the bullet hits a target 5 miles.

Oh and another thing. Notice how Miss Fortune abuses every broken thing in this game. She first abused Arcane Comet, got the keystone nerfed. Now she abuses Dark Harvest, pre rework and after rework so that made her even more stronger than before. And notice how she is the only ADC champion that takes a different keystone from the rest, and also is the only ADC champion that builds lethality.

At least with the other ADC champions, they are tolerable. But playing against Miss Fortune all game makes the game unfun. Broken at S6 Worlds, Broken in S7, Still Broken in S8.
