New Letter from the Producer, XII

[Richard]

Most maps give noting to SP while in party the only thing that give good sp is 10-21 is a type of mob in LL which give 500-700sp. Once you reach 21 finding anything that give over 250sp is hard even with exp chain it going to be dumb sp.

That is why they are redoing mob distribution and maps and adding exp chains. I never said grinding was optimal now considering the highest base SP (WORTH GETTING) in the higher levels is 150.
