PVE Tier List and Guide?

Broken Spaces seems to become a recurring event now. Most of the tier lists I see posted on here are very PVP centric, but PVP staples like IB and DH are pretty useless against marauders and guild bosses. Is there a tier list / guide that is focused for PVE?

From my own experience:

• Most people agree that BB and Walter are the elites, but not everyone has multiple of each.

• People also mention Barea. I have him at lvl 200 with 2* orange gear with max guild stats, and I would say he does good, but not great damage since the last nerf.

• I took the plunge and leveled a Malassa last night, specifically for Broken Spaces. I was pleasantly surprised that at lvl 165, she was already out damaging Barea.

• I would totally put in a Rosa, but the Idle Heroes Gods have not been kind to me. :(

• Also, for guild bosses - when there are 3 of them in the fight, my backline starts to die around round 10-12. I found that putting in an Ormus helped me to eek out even more damage.

That’s it from me. What is your PVE line-up and tips?
