is there some inflation goin on?

I remember a month or two ago, Gc -> sc rates were like 1 gc equalled 80 sc but now it's 1 gc = 140 sc :o

Yeah, I remember that, If you sell GC pls make the price back.

It's how the economy works, the more players, items and such are playing + in circulation the higher the cost of premium currency goes up. The price of SC to GC will go up and down depending on how players value 1GC to SC, economy fluctuates to what people are willing to pay :)
