Advice please on who to level next

[Yeomen42]

I use Sun Quan on my defense team and you can see the red 5* that I have fully leveled. My question is who to bring up next. Intrigued by Roughian and Nurgub. Asteroid? Erebus? I just really don’t have a clue. Alternatively I could ascend Ilmarimen or Zenobia or Zarzog.

Any advice would be appreciated. Am I missing something. Obvious?

Ilmarinen, Asterius, and the new Roughian & Nurgib (albeit don’t know much about this one yet) are all decent options. Mitsuko is also a good offensive weapon.

Any hero that can manipulate mana would be decent option. Roughian since he is fast
