Reworked Cassiopia Miasma Suggestion
I think Cass will be so much better if Riot gave us a minimum-maximum range for her W. Like have the max range be what it is now, but have the minimum range be about half way between herself and max range. To balance it out, maybe have it go in a cone formation, so the further you cast it the wider the spread. That change alone will make her feel so much better with this new kit. Not being able to adjust your W's range is the only thing that I don't like about her.
