The slant being they would only be used for AW
Take your 3/60 Hu Tao to 4th ascension or take a duplicate Chao or Wu Kong there? (I have a 4/70 Chao & Wu)
Take a duplicate Melendor or Caedmon to 4th tier? (I have a 4/70 of each)
Take a duplicate Sabina, Rigard or Tiburtus to 4th tier (I have a 4/70 of each) or take an Obakan, Domitia or Quintus to 3/70? Can only pick one.
Hoard materials and do nothing.
5* - Ares, Sartana, Lianna, Perseus, Leo, Elena
I have one of every 4* except Boril and Li Xiu
I have 30 heroes at 3/60 (probably 6 or so) or higher including many 4/70 (~20) and a few 5/80 (5), so I have the full deck of 30 heroes already
I have enough items to do both without impacting an ability to ascend relevant 5* to tier 4
