Just going to be my own small worded passages for it, updated as I go through it.

Lane Calling 1:
Spiritual Scale (Precision, Root) Moon Knight Starting.
I used Sinister for entire path. Just sp1 spamming and being mindful of unblockable.
Used Silk for Void.
Lane Calling 2:
Lionheart Path.
Rogue Start.
I heavily used Silk in combo with Heimdall and Strikers to cheese the path. Gentle was the worst on the path.
Lane Calling 3:
Scourge Path.
Absorbing Man Start.
Silk the entire path. Simple, Heimdall and Striker to make the Regen insignificant.
Bosses:
Korg.
God this one was annoying at first, tried with Sinister first. Ended finishing with Purgatory.
After learning timings and looking through nodes, I can personally say he's the most annoying of the three.
Need to be on your toes here.
Somewhat strict timers between his Rock Shield to push through damage.
Heimdall.
Purgatory Food. Combo with Heimdall himself (ironic) to tank sp3s. No issues here, just need buff control and not hit block.
Loki.
Used Arcade to pile on debuffs for the Debuffs (3 needed) node. Stun immunity annoying but manageable openings with Strikers.
Not too difficult.
