Almost every character got a buff or a power-up but nothing was done for Tracer. I attack as much as I can but at the end of the match while everyone else has done 10K damage, I have done around 3K damage. Both her damage is low and her health is low. Even a random bullet from Cassidy or Ashe can kill her.
That would suggest you’ve spent far too much time doing nothing, or you’ve missed a lot of shots.
Tracer will be buffed when she needs it. Right now, she definitely doesn’t need it.
