Ok then. Breakdown time:
Most Concord designs are unattractive and non-intuitive. You see an ugly troon in a bright red jacket with Thugnificent 's hairdo and are told this is a sexy rogue (a class that is known for stealth). The designs actively contrasts the class because they wanted to subvert expectations. Contrast her with Tracer that looks like she is a speedy rogue and that is exactly what she is.
Then there is that Amaya chick (the one that looks like a knock-off of a Space Marine). She looks neither intimidating like the Astartes nor as attractive as Zarya who is meant to be an amazonian beauty (a muscular but feminine and attractive woman). Amaya just covers herself in dull looking armor and everything that could make her attractive has been removed.
Here are some videos by a game designer explaining how much the characters suck (since I am aware of my limits):
