I used to play poe on PS4. It actually is a little easier to do some stuff IMO like combat, but stuff like inventory management and menu navigation is treacherous.
You can use your phone to add item filters from pathofexile.com and there is a section for PS4 filters.
You'll have to buy stash tabs/mtx separately on Sony.
If you play poe 2 the market is cross unified, but not for poe 1.
Ps4 and the four tab challenge is definitely a different beast.
Just hit 100 on my Atlas and got my second voidstone. But ive been hard locked at 15 fps (or less) the whole way. Got a new job recently so ill probably have something figured out by next league.
