What are the ranges of edges players should generally be able to accrue (independent of excessive imm xp and the like) through normal playing?
If you look at it as a cost scoring for example
high edge = 8
mid edge = 5
low edge = 3
What is the point range that players would want to reliably receive vs. what to the Imms view as reasonable?

I don't think a char needs 100 points in that theoretical system. I'd say maybe 30-40 would be a good average. If I could take 4 high cost edges on a char, and 1-2 mid or low ones, I'd be more than happy. I could prioritize having more middle edges vs. fewer costly ones. Players would (and rightly should) have to engage in some cost benefit thought when making edge selections. Maybe not to the degree they currently have to, but in the original system with PK EP it was almost non-existent, because you could always amass more EP so easily.

Umi's removal of PK EP was generally viewed favorably, since it definitely fostered #### behavior by players.
Umi removing OBS/Explore was very favorable, just the lack of an immediate source of replacement EP annoyed people.
