There is literally no economy in d3. Pick up decisions really matter in POE. Over the course of spending a 100 hours playing a league it could mean the difference of 100s of chaos.
I get that efficiency and maximization of wealth / hour is the focal point of endgame PoE (and generally most grinding games), but I still think that PoE would be better with a few QoL improvements.
Even with a level 89 I still consider myself a novice to the game, but I feel like I'm trying to strike a balance between actually enjoying the game and maximizing my revenue stream through identifying rares and dealing with currency. On some maps I'll just skip everything except expensive currencies just because I get tired of dealing with picking up a few items before my inventory is full.
I know that GGG has their vision and won't depart but I'd prefer:
1. That currency could be looted directly into your stash.
2. That they severely reduced the quantity of items and matched it with an increase of likelihood of high-value attributes.
And outside of PoE I also bet it'd be possible to improve that PoE trade macro AHK script in some way to locally cache prices from the stash API (or more likely, process them in a third party site like poe.trade, then send digested pricing schemes to clients), and provide live pricing inferences to users upon mousing over items. Even a low-granularity estimate of <1 chaos vs 1<10 chaos vs 10+ chaos would be incredibly useful, especially for new people.
I don't even think it'd be that hard to beat the kind of estimation that every player does.
