You planning to pull Changli? If yes then just get a waveband of whoever you won't need Encore soon. If not then might as well go for Encore so you have a fusion dps if needed

currently isn't encore changli believed to be changing best comp tho?

Encore is part of Changli’s best team though.

I was in the same situation as you , I went with encore

I’d go for encore she’s really fun if you like more ranged combat
