Gunslinger since pre patch (sh/out to The Farmer)
Well first of all how long you've played the character makes no difference to how good you are with him or how good you are in certain matchups with them, I'm a day 1 K N I F E B O Y too. But secondly it honestly is a matchup that's in Kano's favour, you sound like you have a real problem with the matchup which is confusing (at least to me) but also more reason for the community to discuss the matchup so all the Kanos know how to handle it and we're here to help you with itI feel like you either don't play against really good Cassie's or your some kind of Master Kano because I'm no easy win as Kano, I've worked with him everyday since release.
I struggle heavily against good Cassie players.
The character is broke man. Stupid broke.
Just because people aren't using her much yet on the major scene, doesn't mean she isn't broke.
She can easily win this MU, easily. It's not a favorable MU.
I don't even feel like getting into everything you put because there is do much I disagree with.
Regardless, I'm going to keep working at it till I figure it out.
Thanks for the input though.

As for the remark that I might be playing bad Cassies that's not true because the only Cassies I've fought are from TYM. My training partner mains Cassie too so maybe it's because I know the matchup so well lol. This just comes down to you I'm afraid, but that's not to say you aren't good because we have played before once if you remember

Cassie is annoying if she gets in but if you zone her out properly she shouldn't bug you most of the time. But by no means is she broke. Yes she has good mixups but her damage output doesn't match up to Kanos unless she's got you in the corner really.
After reading what everyone else has to say I'll retract my statement about the footsie game for now but they do both have really good footsie tools. You've just got to make her take risks, abuse your walkspeed and whiff punish/trip guard as much as possible because Kanos back walkspeed is actually probably better than people realise. Also if you neutral duck it slightly decreases the range at which her B1 will hit you so keep that mind as you're playing around the neutral. Don't be afraid to poke if you see her getting too close because it will actually help keep her at bay. You want that space as much as possible because if she gets in she will become as broke as you're making her sound until you block and punish lol.
I'll leave you to it though, I'm sure you'll come up with something but if you need help we're all here for you
