Geoff said she was going to receive a change together with other heroes but when the ptr went out she is nowhere to be found in the patch notes.
Are they considering changing her buff?
Maybe a increase to her health by 50 shields, reduced tp deploy time and reduced cd on turrets would help her much more than a damage buff(she already deals a lot of damage she just needs a little bit more safety when doing so).
Thats what most of the Symmetra community would like from day 1 and she would be fine really.
Give her a try on PTR, it’s fairly clear if you play her at all that the charge time has been buffed. I understand you may have been waiting for an official note before trying her out, but I suggest just trying her out.
