I currently have joon and inari fully levelled. My next choice to ascend is between white rabbit, vivica, justice, and leonidas.
My current 5*s are:
Khagan, azlar, elena, natalya (need rings), captain kressel (needs rings)
Mother north, kadilen, elkanen
Misandra, isarnia, magni
Sartana, obakan, quintus
I have all the classic 4*s and many specials.
Im leaning towards Justice since i dont have any high ranking paladin heroes and mother north will be my healer.
Thanks for the advice!
