Well yeah, price is rising But should'nt that encourage people to RC more and buy the runes less? They just don't buy Profit margin is narrowing though, since pure essence has been rising also, usually at a faster rate. People are crafting fewer and fewer natures as RC, even at 91, is no longer amazing money. Actually, you can now make around 1.1-1.3M gp/hour with 91+ runecrafting instead of the 950K/hour when pure essence was 150gp each and natures 230gp each.
