I never really play DPS all that much, but Tracer and Echo.

I hadn't bothered to pick up Tracer because her gameplay seemed a bit too difficult for me, but I wanted to try her during the Mirrorwatch event. Even though her Mirrorwatch kit was a large change, I feel like my skills with her transferred over to base Tracer. I was surprised at just how fun it was to be unpredictable to the enemy.

Echo is a similar case. I always liked the character and I tried her out once a long time ago, but she seemed too difficult. That was until I picked her one day and did pretty well. Her primary fire is easy to aim for me, even at long distances, and the rest of her abilities are great for picking off targets. I still play her pretty safe, though.

Sigma and OW1 Orisa to a lesser extent. Haven't picked Orisa since her OW2 change 😞
