Currently an ses about 130 rp, and ases 3-400. If it takes an average of 2.5 or 3 ses to make an ases, the system would currently be pretty balanced. How far away from those values do you think things would deviate if the ases recipe comes in to the game permanently?

There can only be so much of a combined change of ses price going up and ases price going down before this recipe just becomes not really worth using...meaning things won't change much unless adding another sink for regular ses somehow makes their value drop as well.
