I kept her for far longer than most 2s simply because for ages she was my only Rogue. Then a couple of 3s appeared but I kept hold of her for trials because I never had anything decent to use, despite having 4 and 5* by that point.
Finally I pulled Kelile and then 2 Scarletts and from then it was only a matter of time before she had to go. Also had a soft spot for her but didn’t have the roster space to justify keeping her.
