Currently, I have the mats to raise a 5* to 3/70 or a 4* to 4/70. The top row shows my current yellow heroes. While I wait for darts to ascend Vivica, I’m not sure which yellow to level.
Since it will be a while before I get darts to ascend another 5*, I’m thinking it may be better to max a 4*. However, I’m not sure that either Chao or Li Xiu would be better than a 3/70 Joon.
That said either could be more useful for challenge events and raid tournaments as they can be used for 4 and 5* events/tournaments. (With pirates coming in March, having a yellow stack would be very helpful.)
This makes me consider synergy with my other yellows. If I stack yellows, Li Xiu’s AoE stank pairs will with Wu Kong. However, Chao’s single target attack at fast mana pairs better with Jackal.
Thus, I’m not sure which would be the best course of action.
