Thanks for the reply.

So it seems there is no need for a full categorized list, as the farming can be split in practically "early game farming" and "late game farming".
I'll be editing my ramblings and making them a TL;DR of your reply.

How to best place your teams on 12-3? I have a hard time understanding the pathing but I seem to miss atleast 1-2 chest every run.

Two in the bottom tent, 3 in the middle tent that makes them run downwards. This makes 4 of them all run the longest path and 4 attempts at the leftmost chest.

Thanks just tried, seems to be a really good approach (still missed the left chest on my first try, lol.)

So now with mission 13, is there a better place to farm?

It probably won't be well known until we get an event that doesn't require farming the event maps.

all i know is group bosses are far better but yeh only done 13.1 & 2 no amps yet

12-5 gives i bit more Gold/Seeds than 13-5 and has a higher chance for more chests to get an ampy, but if there is a difference in ampy chance is unknown. 13-5 has a way better RB to share which gives ~3x the seeds than a 60 Wasp, both Discover and Participation.
