I played this game during release and want to return. I have Naladia, Elnora, Trisha(almost 4*, 27 lvl) /Celiim (2* 29 lvl). Leyna (3*, 28 lvl)/Khalis(3* 23 lvl). So i have 2 questions: 1) who should i choose in current patch in wind/earth because leveling them all is too long 2) what set should i focus first (i guess Naladia should be #1 priority). Now we have an event with raid pieces in rewards so i want to get as many as i can.
