As you I'm an old school player of PoE.
• PoE does not have an auction house. Players want an auction house. The developers have said, they will never add an auction house. Here is the trade manifesto for example, which illustrates this.
• Players want items to be easier to pick up. They want loot vacuums to suck in items that are around them. This is another example of something which the developers consider a core pillar of Path of Exile and have said would never change.
• Just recently (as of Harvest League) there was a massive outcry about players wanting deterministic crafting. Deterministic crafting goes against the core pillar that powerful items are hard to obtain and as of such, it is not going to happen.
Not altering 3 things (which I'd hate to have them changed the way they are right now because the game is supposed to be hardcore) when they've done hundreds of thousand other ajustments based in a client base is simply the worst argument in the world possible to justify yours concerning BG3.
Those 3 comments you've posted are like asking Pokemon to remove the Pokeballs. Asking Street Fighter to remove Ryu. Asking Dota 2 to be turn based and so on and so forth.
Why the hell is that comparable to ask a DnD5e game based to CARE about spell balance? lol
BG3 would get so much out of POE
Economy to begin with. Law of Scarcity in economics were perfectly implemented in that game. Scarcity is not a BG3 thing
