@Meddler Will there be any upcoming Lissandra reworks/buffs, and when?

Since, quite a while ago, Lissandra's passive was reworked and it did not make it to live, does that mean that you guys are still thinking about buffing, reworking or changing Lissandra? Do you guys have any ideas of what you might do to her? Right now, she is a bit weak. What kind of changes are you thinking about, and when can we expect them to come out/start to be worked on (as a guess).
