I have a number of 4* characters from $packs and wandering if any of them can be usable despite their lack of stars.
I'm around 100 on my server (same server as WhipIt) and with 19800 power. Currently run phasm/bobba 6*, sid/lum 7*, and 5* kylo.
The Unleveled 4*s I have are Leia, nute, cad, finn, poggle, dathcha, rey, dooku, moff, kit, qui gon, Urrrururwhatever, and a leveled vader.
I think old Ben would be, but never got him
