Well with the heros presented, you have 4 viable tanks:
Kunchen, Drake, GM, and Aegir
Kunchen>Ariel as tank because of his stats and his elemental link to resist holy in addition to his heal and cleanse. Since you seem hesitant to remove Hel (for good reasons) I would run:
Alby-Kunchen-Drake-Hel-GM
Opposing element flanks protect you from dark stack, Kunchen protects Alby and links Hel to also protect her, and dmg output comes from Drake, Hel, and GM.
Thanks for the thoughts. I pulled the trigger and I’m putting Kunchen and Aegir in there and now I’m contemplating swapping out Drake for Onatel because I can take emblems from Hel if she’s not on def.
Love to get people’s thoughts on that additional tweak…
