I haven’t touched the game for months, is there crafting in the game ?
Like actual real crafting with recipes and random rolls ?
Is there an AH like other online RPGs ? Something that leads to an economy ?
If not, I wont bother coming back.
Crafting? no, diablo never had that, I don’t see it needing it. You’ll need Crafting Materials to upgrade things.
I don’t know what “AH” is. Something that leads to the Economy? - what like Trading?
Why don’t you check out season 4 when that releases, if not well bye bye then.
well there will be tempering and masterworking which are similar, both of which coming to S4, watch the latest campfire if you want more info
no AH though.
hello and goodbye 
Nope.
No AH.
No crafting.
But there will be some big upgrading in S4
No AH, but they are now adding trading of legendarys and uniques (just not uber uniques.) Basically they are making a step in the right direction for an economy, in s4 if you find a good legendary item with a couple GG stats on them RNG rolled into the super versions of them which is rare, you can trade that and probably for a crapload if it’s truly a meta item. Can also trade your typical uniques like those thorns users can buy a razorplate early on, if you find a near perfect unique it will probably keep value, but I don’t suspect uniques will hold their value as much long term since they drop like candy eventually.
As for crafting, the new system is you find a legendary with 3 mods on it, you can reroll one of those 3 mods into something else, you can “temper” on 2 more mods so 5 mods total, but the tempering is a bit RNG and you only have like 5 chances to get the mods you want so there’s a brick potential here. Then if you got the mods you wanted, you can masterwork it up for some more RNG of having the game pick the best mod out of those 5 to get a bigger boost than the rest, again good luck but you can’t brick on this, you can retry, it’s just a money sink if you keep retrying for something specific. You also add whatever aspect but that’s guaranteed process.
The game isn’t like PoE for items, but I think s4 is moving in the right direction for both trading and crafting personally. I’m gonna give it a try at least.
