Hmm, lots to think about.
Laying out the pros/cons of each option clearly is definitely appreciated Yrs.
I'm still on the tourney route but I can definitely appreciate the diplo route more now. Maaaayybe I could be convinced to change but my thoughts on the matter now are:
Access to sect elders, challenges, and training seem really really important. The ice ladies route would I think offer insights into domain and the world yes, but we will get those irregardless. Whereas access to high level cultivators who are willing to (mostly) freely share information, training, insight, etc. just isn't going to come outside of the sect.
I've also really wanted to do some exploring with that map. Like, ever time we've opened it something really interesting has happened. Could we this turn devote time to exploring the map? Just for funs. Given the moon link it could definitely lead to opportunities to working away on that heart demon which is something to keep in mind.
At some point we are going to have to go prospecting for our fief irregardless so getting to do that a little sooner doesn't sway me over much, while loosing access to our friends earlier is definitely a big downer for me. Basically, the stuff we get access to early by going diplo doesn't sway me cause we get to do that anyways later, whereas the stuff we give up early by going to diplo are all things that we can't get access to later.
Apart from the map and heart demon as above I don't have a huge preference as to the plan/cultivation for the next turn so I'll just lurk on that and see what the spreadsheet cabal comes up with.
