Merchants

One of the best changes you guys made was to making merchants' items meaningful. In PoE 1 it felt like merchants were useless, but now they are really important. You can consider introducing even more powerful items to merchants, like uniques or something. Good job!

Interesting idea. I’m also in favour of some way (not for free) to restock the merchant (since leveling can sometimes not be the ideal way to reset them)

And they start to feel useless again after completing campaign or going into higher tier maps, so GGG could consider improving it in the future..
