You analyze certain characters but still fail to do so? Alright let me spill the beans because you seem so professional in understanding how a bug did “no impact” and it’s all just “everyone L2P”.
It’s really that simple: She can close the gap and escape better while still maintaining blinks.
On top of a different bug that made her melee to literally deal 15% more damage because it applied armor first then damage that’s also getting slide in as people L2P, Tracer whole rework was bugfest nonsense and thus her entire win rate was heavily inflated in the process.
This alone is not just “nothing” this is a literal game breaking bug(s), a soft patch to mobility that was lost in the rework back then with a bug, a literally chaotic and very effective bug that makes her preserve blinks for more usages, it’s simply not “people learned to fight her” it’s the other way around, a bug has been fixed and now she no longer has a considerable massive mobility power spike all of a sudden on top of actually being more alive and maintaining untouchable stacks.
Your inability of understanding this specification is what turns me off so much with frustration that shows to me you have no idea what you specifically talking about and just making it that people L2P, what do you think people all of a sudden ban a hero because they don’t want to fight then next patch she just keeps declining in ban rate because they L2P or the fact a game breaking bug fix is no longer making her a massive threat? Let alone breaking another interaction with Get Stuffed where Heavy Handed being comboed with it no longer increases the Pulse Bomb damage (gosh being a main of this hero is such a pain 
) It’s because of these stupid bugs.
As for cassia…
Your way of dismissing everything as an L2P is also just sad, you aren’t going to consider that Cassia’s survivability is over the top hence why she’s literally over performing everywhere??? 58% in all SL games combined? 59% in masters??? This looks to me like Zarya’s first emergency balance patch all over again.
Masters:
Fun fact (and it’s a fact): That was 59% yesterday, now it’s 64%.
All Ranks Storm League Only:
You keep saying that while ignoring those stats, you aren’t even responding to my last 3 - 4 claims of showing literal proof that you can look up but still throwing out L2P issue in constant rate.
And you are also making things up when the stats are right in front of you.
I don’t care how much about how much damage she deals or take because I very well know how to play her and already addressed this multiple times in many topics and even made a fully fledged guide, 100 times better than what you are throwing around about her especially in the other topics you’ve discussed about Tracer.
Because I even wasn’t being specifically biased over my main when she was the spotlight nor was considerably denying that she’s “overtuned” much as you two are doing right now.
And placing issue discussion as people wanting heroes to be butchered is also very unhealthy way of discussion, you do not want to literally discuss it you are just simply throwing claims that makes no sense with what we have in literally 2 weeks of crap ton of games played making her top of the 3 most played in this match in masters alone, you know the same rank I literally play all the time?
I despise people who want heroes to be nerfed because biases but I also hate those who live in this weird bubble as everyone else keep showing actual proof of stats on top of those who just simply want to nerf the hero because “anti fun” or any of this nonsense.
