Given the recent updates (especially the new gems, the account\character bound gear and the nerfed rates of catalysts) I would suggest adding some options for premium trades and some new items for the premium shop
1) All the enchanted stones should be tradable for premium points: with all these new gems and the trend we're going through with gems, the desiderability of the enchanted stones has dropped significantly. I say we should be able to trade 4 stones of the same kind to 100 points (the rate is just an example, but it pretty much goes along the lines of the current rates)
1) Jupiterunes and Saturunes should be able to be traded for Premium pts too (with jupiterunes taking a much larger amount to be able to trade, say 500 per 100-200 premium)
As for the premium items, it would be nice to have the ability to buy
1) Venurunes
2) Plutorunes
3) Nepturunes
4) Item Unbinder Coupons
5) Reroll Hammers
more could be added but this would be a nice step forward already.
Feel free to add your thoughts.
