If PoE 2 is to replace PoE 1 in every sense—dramatically visually and systemically continuing from where it left off—then one need look no further than the in-game economy. While most RPGs rely on gold, the majority of the PoE bartering is made through crafting components or, more specifically, orbs, shards, and scrolls. This gives rise to an in-depth structure wherein almost all items that drop at the end of a game have value either directly as gear or indirectly as PoE 2 Currency . 

The trade experience is one of the most defining and divisive features of PoE 1. Though frustrating at times due to a general lack of an immediate auction house, the current system succeeds in its place by enforcing a very crucial element of friction: if trading were instantaneous and automated, the true value of meta-defining items would plummet, and that inherent feeling of excitement upon finding a rare piece would be gone. 

Furthermore, PoE 2 needs to learn from the "complexity bloat" that plagued PoE 1's later development cycles. Over time, GGG layered dozens of league mechanics onto the core game, making it an overwhelming experience for new and returning players. While deep endgame content is vital, PoE 2 should launch with a focused, cohesive Atlas and a manageable number of core systems. The depth should come from the interconnection of mechanics, not simply the sheer quantity of them piled on top of each other. The endgame must be earned and understandable, not instantaneously overwhelming.

The early game of PoE 1 is notoriously sluggish. It often feels like Act 1 is a huge hurdle for new players before they even get to experience the depth of the skill tree. While PoE 2 is already remedying this somewhat with improved combat responsiveness, it needs to tighten down the early leveling process. Quests and narrative delivery need to feel modern, ensuring smooth progression and clear direction so that players do not get early burnout and stick around long enough to enjoy the more complex elements of the game later on.

PoE 2's design will seek to retain the spirit of its predecessor while increasing its scope. This cannot be done without preserving the mechanics that drive player incentive through the discrete economic engine. Everything, from item drop rates to crafting requirements, has to be considered in terms of how it interacts with the player-driven economy. It is precisely this scarcity and diverse utility of the path of exile 2 currency items that maintains the game's longevity, making their protective integration into the sequel an absolute.
