I use her as a TW cleanup with Savage and Sass to finish off a weakened unit or three. Sass deals health damage, Shan controls, Savage executes. Throw in SiT if needed. (haven't needed it for GA, yet) I haven't thought of using it as a straight up offense, but I don't have zmaul and these guys aren't geared too high for me
In however long it takes to get like 100 Traya shards or so, I'll probably gear her up further and put her on the Traya team. She occasionally subs in for Thrawn on my EP team
