This was never covered in the patch notes so I can assume it is a bug. When casting the symmetra photon barrier, it is noticeable in comparison to prior this patch, that the symmetra wall cast time was a lot slower beginning with season 3. It feels weird and laggy to an extent and does not feel intended to her kit, as the wall takes maybe a second or so longer to come up for when the player wants it.
Did Blizzard hotfix this? I just played some games with Symmetra and I’m not getting the bug anymore. I was yesterday.
