R5 unduped Gwenpool or duped Black Widow/Panther?
So I've got 3 T4 Skill class catalysts and am looking to see which 4* would be best to rank. I don't have any Skill class 5*s but the 4*s that I have that are 4/40 are unduped Gwenpool, duped Black Widow and duped Black Panther (Civil War). Which one of these would be the most worth it? I'm leaning towards Gwenpool because she's one of my faves and is amazing but BW and BP could do well in AW defense..
