So the did a AMA and I noticed this in there.
Question : I have to ask - what is going on with Symmetra? She was weak, then buffed, then immediately reverted, now silence. Is she getting reworked? What data shows she needed a nerf? She is super weak and hard to use on ladder (uncoordinated environment by nature) and was only played in OWCS for Mauga - shouldn’t nerfing Mauga have been enough?
Answer by Alec : Symmetra kept some of the buffs in that patch but yes we hear the feedback of where her current power level is. We may have been a bit overreactive to the Mauga compositions popping up during that timeframe (he was certainly overtuned), but we wanted to be sure of it. For right now, we are in discussions about Symmetra and especially her frontline presence. Believe that’s a piece of the kit we’d like to promote further, whether through her survivability or beam damage.
So they all but confirmed that she got nerfed because of mauga. Not because she was strong or OP, but because of mauga.
Please excuse me while i go back to crying.
