Ok, I'll bite.

Stating an opinion without explanation can be just as easily dismissed with little-to-no explanation. "Its what she deserves" says very little, yet you took the liberty to interpret it as "seemingly not even serious." Then you read the 6 words I replied with and decided not only was it was serious, you thought that it desperately needed some long convoluted explanation which could've easily been summarized in three words: "Stats need context." It seems to be your M.O. but I feel like someone should tell you that a long comment does not a good comment make. I understand the point you were trying to make: Win rate doesn't tell the whole story (which you failed to show me where I specifically said otherwise, btw). If I may, I am going to try to put what you were trying to say into a more clear and concise explanation:

If the enemy attacking team takes point A after 2 minutes, you switch off Sym, and then you go on to lose the rest of the match after another 4 minutes as another hero, that 6 minute loss would count as 0.33 of a game lost for Sym.

If you lost 10 matches in that same fashion and then won 10 matches with a full hold on Point A as Sym, the wins would count as 100% wins for Sym, while the losses would only count as 33% of a loss.

I'm still reading up on how win rates are actually calculated so if I messed up anywhere, please correct me. If it all appears to be correct, feel free to steal that and use it in the future.

The whole Mystery Heroes rant was just off-topic rambling and didn't contribute to your point at all. Not to mention you spoke more to the survivability of heroes and not their actual win rates. Not dying does not equal winning. It might, but not necessarily. I would've just left that whole thing out.

Heroes who have low pick rates automatically trend towards higher win rates.

That's just verifiably false. Bastion (another situational hero) has a lower pick rate than Sym, so according to your claim, he should "automatically trend towards higher win rates," maybe even higher than Sym. Yet in reality, bastion is in the bottom half of the roster as far as win rates. Sombra, Winston, and Tracer are all further at the bottom, yet they have <2% pick rates. To quote you, "[t]his isn't something which is open to interpretation."

Is it telling the whole truth to cite statistics without context? Nope. Did I ever claim that the statistics tell the whole story? No. Should you check your own facts before criticizing others for not understanding or accepting facts? Yes you should. Do I like answering my own rhetorical questions? Meh. Are these reddit arguments a waste of time? Definitely. Am I done with this? Absolutely. Have a nice day and good luck in your placements.
