So energy cost.
200 energy, .75, that's about 38 cents per 100.
750 for 2.50, that's about 33 cents per 100
1600 for 5, that's about 31 cents per 100
3500 for 10, that's about 28.5 cents per 100
7500 for 20, that's about 27 cents per 100
20,000 for 50, that's about 25 cents per 100
... so I know these are nice round numbers, but the first observation is that the unit size was 20-25 cents per unit for YPP, and is 25-33 for SK.
Is the energy per pricing point too low? Should you get more bang for the same buck?
===
Entirely separate: What is the expected/intended crowns per hour of play for SK supposed to be, and how does it compare to the expected/intended poe per hour of a YPP pillage?
(Trying to get some sense of where the exchange may end up pricing in the future.)
If you compare everything to YPP then it's better for you to play that instead..... if you think everything here should be like YPP then you really should just play it and stick with it.
Also I would like to remind you again this is a preview, nothing is solid as of the time been and if the system needs a tweak it'll most likely going to get it during a more formal lunch.
You'll also have to consider what would happen when the economy of SK grow and what things would it change.
