For Zenia , I would wait for as long as you can before picking her , since we have no idea what her kit will be like . Also , I could be wrong , but I don ' t think there ' s a set date for her release . 2 nd Azurai is a solid choice if you need help getting more wins in Hero class . I ' m not sure you ' re lacking any particular buffs , but you could pick Felice or Sirius for a better BC on Spark buff . Felice in particular goes really well with Azurai , if you use him outside of Colosseum at all . You could also consider Kanon as a future upgrade of Kulyuk , but his OE isn ' t in Global yet . Alternatively , Elimo for future hard content if you like her kit nonattacking HoT , burst heal , cleansing , defrec buffs , potential EWD null , mitigation , etc . Her OE will arrive sooner than Kanon will and she might be good if you want more mitigation options .
