YES! She is unkillable, thanks to her unbalanced abilities. These comments mentioning how much health she has are hilarious, because that 150HP means NOTHING thanks to Recall.
She is a pain to kill because of Recall regaining health, and Blink's cooldown being too fast. And before the "counters" get mentioned, Tracer can get away from Mei and Winston without so much as a scratch. Mei & Winston's weapons aren't effective enough against her. These people that say otherwise about a Tracer nerf, just wouldn't be able to adapt, they'd suck with Tracer if she was actually balanced.
