I wish they would have done it like Guild Wars 2 instead, reach a certain point threshold and get a reward.
e.g. each 1000 points or 2000 points you get a part of an armor set or whatever else, at 5k a mount and so on. Would entice people do do achievements even to get more points right? Thats all you want to have as a MMO, binding your customer to the game...

Instead of giving us a currency for a shop that will never have enough items for it. And therefore doesn't create any motivation to go for more than needed.
