Not true, Tracer’s Recall cooldown is twice as long as Sombra’s Translocator. Tracer’s Blinks are equivalent to Sombra’s invisibility. Sombra’s disengage is far more consistent. Tracer Blinks don’t really allow you to full disengage, only reposition.
Your whole take is incorrect. Why don’t you see if one tricking Tracer increases or decreases your rank compared to Sombra.
