People Play Symmetra Wrong

No, they didn’t anything about this. There was no expectation stated by Blizzard; you, however, are making this expectation for yourself.

No, they did not state this. They changed the teleporter to be able to have the option of controlled self-destruct, giving more control to Symmetra’s teleporter; this required a change to how the cooldown works.

More supposition and conjecture without factual evidence.

Ditto here, too. You clearly make these stupid mistakes all the time indicating bias that you think you know better than what Blizzard, the game’s creators, do when it comes to their designs. You are acting entitled; and it is easy to dismiss this argument.

You don’t have one bit of evidence or data-gathering to indicate what Blizzard did was wrong. This still reeks of entitlement bias.

Supposition without a basis of fact.

More supposition which concludes

false conjectures. Defense is a real element in the design of Overwatch. Keep targets out of your controlled space or objective is a benefit to you. If they can’t approach, that’s good for you. The more time spent fighting away from the objective, the less time they have to capture it.

Ignoring some of the obvious faults in map designs. Defense is oriented to stalling and delaying until the timer runs out. It’s a beneficial design element to wait it out or find ways of bring the enemy to you in the most dangerous ways possible for them. Offense has to take the risk, defense does not have to give chase or mobilize anything or anyone to hunt down enemy targets. At best, they can sit on the objective all game and stall until the enemy offense decides to move in. That’s beneficial to a number of defensive minded heroes, including Symmetra.

Irrelevant in defense; which is Symmetra’s primary design role. See above.

Irrelevant. Stay focused on here. Complain about the shortcomings on OW2 when OW2 is here.

And it did it’s job, but that doesn’t change the fact that Symmetra is largely going to be focused on defense, area and spacial control.

Emphasis mine.
