This isn’t a solid claim, with Tracer’s Great DPS, comes great weakness. Her low health has a lot of penalties.
- Blinking into say, the wrong place at the wrong time, like a Reinhardt swinging his hammer (which can 2 SHOT you.)
- Healers don’t always pay attention, Mercy can heal you in about 2 seconds.
- Her low health is the reason she has self sustain (or vice versa)
- Her Recall already has a decent cooldown, It’s not like she can do it for infinity.
I think Tracer is in a good place. She just needs a true counter, and that’s why you might think to gt rid of her self-sustain.
