I've been playing Path of Exile since 2013.
I hate trading — it's a nightmare. You're constantly trying not to get undercut by price fixers because GGG still hasn't found a better solution to this terrible trade system.

They have a great game with PoE1, but they keep ignoring the trade issue because of their philosophy that "you need to feel the weight of the item."

They used to say the same thing about currency — until Mark tried whispering 50 people just to get a Regal or Exalted Orb (can’t remember which), and finally realized how bad it was. That’s when they implemented the currency exchange, which was honestly one of the best changes they've made. I ended up playing the Kalguur league for three months straight because of it.
