The main 2 reworks I want to focus on are Mercy and Symmetra. Neither of these reworks helped. After all of the nerfs, Mercy is similar to 1.0, and Symm is similar to 2.0 (win % wise). They have these ideas and visions for heroes but they have trouble executing them.
As a Symmercy main myself, I believe that the Mercy rework was 100% unnecessary. They just needed to tweak some aspects of her ultimate. The Symmetra rework was somewhat justified, as she was extremely difficult to pull off in some situations. However, they removed the aspects that we loved about her, like her lock on beam, piercing balls, and shield gen.
Both of these reworks clearly ignored what the playerbase wanted, and the devs went down their own path of what they thought was right. While I understand that in some ranks Mercy 1.0 was a niche pick and Symmetra was a niche pick in every rank, they still shouldn’t have disregarded the thoughts and opinions of the playerbase, no matter how small it is. They struggle to maintain the identity of the characters when they rework them, but they try and force it. Take Mercy’s rez. Blizzard was so persistent on keeping it in the game they sacrificed every part of her kit to “preserve her identity”. Yes, her Rez was her most iconic move but they made it bland and horrible to use and play against.
I’m not sure if I’ll ever fully trust Blizzard again due to this year of blatant disregard for the community and the constant nerfs, but they need to do what’s right and either revert Mercy with some tweaks or rework her again.
