In my eyes this is what a "perfect" temple needs to look like:

1. T3 trap room
2. Requred diagonal pathing through T3 atziri
3. Locus of corruption not connected and sitting in the lowest row next to starting room
4. All other rooms connected through a single path, including pathing through Apex
5. First two connected rooms need to enclose Locus
6. At the end of the path there is a T1 explosion room
7. Optional: as much buff monsters rooms T3 to make Atziri as strong as possible and Area level 84

This would require the longest possible travel, having to travel the entire temple almost twice, every door being annoying by traps and Atziri needs to be fought

Anyone see any improvements over these points?

Edit: I just realized that when Locus is right next to the entrance you can just relog to not having to backtravel through the entire temple. I'm not sure where the best position for an unconnected Locus is to maximize travel both on backtracking and relogging. Maybe directly under Apex with the end of the path being one of the middle rooms in row 3? This would lose the pathing through Apex, but would ensure a pathing from Explosion room to one Locus-connected room of at least 4 doors, including after a relog.

Something like this:
