In HSTR she is not needed - she doesnt outperform r2d2, however she is useless in any other phase so you can use r2d2 later on
As soon any debuff sticks on her she wont use her special nor she will riposte. As all Sith debuff she is crappy in many cases against them in reality.
Against KRU as soon she will be forced to attack him, he will give her as riposte a debuff and she is again crippled.
Her heal has a very huge cooldown, even it gets reduced it doesnt work well in Arena unless you are able to hide her under r2d2 cloak for example. Her kit is not well thought apparently - she could be good, but she isnt and she also is very buggy as her heal counts protection+hp and so often she wont even heal anyone in p1. Do not buy her and if you really want to farm her, be warned that she underperforms outside of p1.
