You didn't forget, you just had a relapse, it's normal, it's happened to me. What made me play well again was taking a little break, it worked for me, don't think that way! You play and have always played well with her, you just had a relapse like me and other players 🤗 I recommend playing with a hero that interests you, and taking a break with her, when you feel that urge to play with her again you'll see that it helped you a little. I won't lie that in the first few days you'll have a little difficulty hitting different combos with her, but don't think that you forgot how to play with her, that's common ❤
