I was trying to complete “Uprising” (story) and noticed Tracer is so bad to use there she becomes trash, especially on last section. Granted, the players who played her were crap but she is bad from a distance and there was no much space for her to maneuver and was disastrous to kill Bastions and Orisas. In fact most of the numerous failures I had with the teams (always with randoms ) started because Tracer died. Fortunately I managed to finish “Uprising” on Specialist with a really good team of randoms, in spite of Tracer.
Tracer must have been nerfed badly to the point she is just trash to play in this particular mission. She is still fine in “Storm Rising” since there is much more maneuverability there, but in Uprising she is a pain. Blizzard, buff Tracer!
P.S.: I noticed the mission was designed with OG Mercy in mind, where she used to be able to revive all allies around her from some distance.
