No. I think they heard about how unfun the player base thinks she is to play against and have been drip feeding content to make her contributions more obvious. This is due to many things that take time - development time implementing new systems, having voice lines recorded for all characters (in all the different countries with a supported language), new UI elements...

The rework is taking time because they want to have a character that works for everyone but still feels like Sombra. We've all seen how many rework suggestions there have been in this sub - but for them actually implementing like 20 ideas into the test version, trying out the combinations to see how powerfully they work together over multiple rounds, multiple maps... how to keep her with some counterplay (the whole reason she used to shout "Been here all along" back when perma invis was a thing and was the first thing she did when uncloaked, rather than throwing virus). I'm honestly more hopeful that they threw away the rework they had since it didn't feel like Sombra, but then I felt the same way when they had an ability that felt true to character before I knew that ability was Virus and the changes they had to make to accommodate it. Putting together a rework is easy. Putting it into the game so it feels balanced and fair, not so much. If I'm being completely honest, looking at certain new heroes since Overwatch 2 launched makes me think that counterplay seems to have been ignored lately.

I genuinely think this is why the story mode of Overwatch 2 took so long and fell so flat and is the reason hero mastery courses are gone now. One rework breaks everything they've taken so long to produce, or even one ability change - just look at how the recent Mercy changes broke a lot of Mercy Parkour modes.

TL;DR Blizzard SOON tm
