You directly said these things were tradable. That allows a single account to store more power/make it more capable of something, it is giving a very clear advantage, based on your own wording, to trade for power.
Also you’re ignoring what I’m saying as it relates to it being non-deterministic. THat’s precisely my point. You need an item to start with to get the god item. The more base items you can store to craft the perfect one, the more shots you get at making it. It becomes a direct ability to craft the power you want. I feel like at this point we’re going in circles. The fact you may not get it is irrelevant. The fact is you can get more shots can get you closer even if it’s not quite what you want.
You can like POE. it’s fine. But it’s naive to think that they’re not selling an advantage when they clearly are.
