I've been with Path of Exile: Siege of the Atlas for a few days now, and I have to say, the wait was worth it. I can briefly say something new for you guys. The regional Atlas passive tree has been replaced by a giant Atlas passive tree.
And Archnemesis Challenge Alliance, allowing us to customize rare boss battles to control risk and reward levels. And when we have more Exalted Orb, we will find that their game experience is better, and it is easier to get the most valuable rewards.
I believe this is also the reason why many players buy POE Currency. Me too, I frequent POECurrency. Their prices are really cheap and being a VIP member gets extra discounts, so I've joined. I've never been banned for trading with them either. This is really the right choice.
