Even with her nerfs ( it was bad she countered Rein), I think she is in a good state and saved the support experience of OW.
She counters dive tanks which was needed, and more importantly can force retreats on Flanker characters.
I think it’s fine she isn’t a hard 1v1 counter to the flankers but she’s so reliable at giving them pause and forcing a disengage which is paramount when playing support. It is also fair for the DPS because now they can play a more straightforward DPS char ( McCree) to counter her, and can outplay her if they are aware of her cooldowns.
Supports finally got the peeling hero we so desperately needed.
To all the Brig mains who would complain about Tracer, let me tell you, you can still counter Tracer you just have to have as much awareness as she has of you ( i.e keep track of her blinks, rotate your shield to cut off her angles and SB her to force a recall and she’s gone, also calling out her position and having her stuck on you makes her an easy target to kill for your team).
I’ll concede her kit was overtuned ( this is coming from someone who despise DPS Mains) but I really think the problem was overall Tank+Support synergy and that’s moreso the fault of blizzard ( i.e they removed too many FPS mechanics from those roles and made it heavy on ability/non-fps mechanics reliance).
I think having her in the game that gives the support role much needed independence has allowed the game to finally not be reliant on one role as much.
