@Hybridplug @scuba thank you very much for the insight. Honestly, since I do not have GK or Chaze, and also Cassian for that matter, I never thought that she'd be a better lead than Wedge; I just thought she might be good with a Wiggs lead. My shard has gotten a lot harder lately and I am finding myself struggling to sneak into the top 20, as I was usually in the top 10/ top 5 before, so my lineup needs a change and was wondering if Jyn could be it. But reading your post as well as the others, I'm realizing that I'm probably better off to invest my resources elsewhere. Thanks!
Now I got to get back to polishing off my mods for TFP, Boba and Vader... ;)
