Every time they try to change Symmetra to make her more broadly useful/appealing, her three mains come out and complain as loudly as a mob ten thousand strong.
Symmetra’s current niche as a shield cracker is good for OW1, but in OW2 she’s going to struggle a lot with her criminally short range, low mobility, and low uptime on her utility skills. She definitely needs a rework, but the amount of effort going into making Symmetra good in a faster paced environment is basically making a whole new hero–Bastion didn’t need New Hero levels of adjustment.
