Is Black Widow seen much in Diamond+?

Just curious because right now I'm a plat BW main steadily climbing. I'm questioned on my pick at hero select screen a lot. I've steadily climbed but obviously its slowed down a bit the higher I get but she has clearly worked for me so far. I play about 80% BW and the other 20% is Psylocke or flex. People make her sound extremely off-meta yet she's working for me so far. I don't believe meta applies until you hit diamond so I'm just wondering if there are any diamond+ widow mains that aren't struggling because I don't want to throw games once/if I hit diamond.
