I like to start on a x/4+/2+ location and I'll generally CTRL-N till I get one.

I got sick of that and now I modified the elementaldefs.xml to only show minimum production of 4 and only manually decrease tile yield at 15 (trying to get some higher essence tiles). 

It feels more broken than I would like - there are now 6/4 and 5/5 spots.   I'd just really like to have a good start location and then all the other settle locations be natural.

Any recommendations?   Specifically to get at least a x/4+/2+  but if possible also to generally increase the essence yields.

I don't have the pertinent fields front of me as I'm at work.
