It's not about progress it's about builds. Weird gimmicky builds that are are possible w/ very specific items and very specific affixes on said items (the Sacrifice builds). The only way to ever try out these builds is if you somehow find these items, and that seems "remote." If it's NOT remote, then you've run out of stuff to do already, b/c they refuse to make any kind of endgame that doesn't involve looking for more items.
As opposed to what?
Personally, they should have kept the AH, but introduced Bind on Equip, or Bind on Sale. You can either wear it or sell it, but not both. You can buy it, but then you can't resell it. Something like that. They needed an item sink, no question, but this seems extreme. This is like the console version, where you find what you want immediately and now have nothing to do. I guess the biggest elephant in the room is the lack of a non-item oriented end-game. There is no PvP and no raid system. There is nothing to actually do w/ the gear you find. Gear needs to be a means to an end, instead of the end in and of itself.
All legendary and set items being soul-bound is a terrible idea. Don't kill trading. Killing the auction house is good, killing the social aspect of trading is bad.
Going to have to disagree here. One of the worst things about D2 was trade spam, scams, and sitting around in lobbies yelling "10 SOJs for Tal's Helm" for hours.
Trading in Diablo is one of those things that sounds like a good idea on paper but doesn't really work in practice.
The devs have it spot on in my opinion. I don't want to spend time in some sort of trade chat spamming for the item I need. I want to go out there, kill demons, and find it. And then enchant it to make it perfect. And then use it to go out and kill more demons.
Due to RNG, do you even know if you'll ever see it? In D3, I've found multiple Andariel Helms, Manticores, Zuni's ring and boots, Tal Rasha helms, Nat's boots and weapon, Inna's weapon, and every piece of Immortal King. I have NEVER found, on my own, either Chantodo piece, Uhkapian Serpent, Skorn, Tal Rasha chest, orb, or amulet, Zuni's mojo, Echoing Fury, or Mempo, let alone the "good" versions of all of the above.
No, you haven't. Most people haven't, because the droprates for legendaries sucks right now. That's all changing with 2.0.
But the real point is that the item hunt, in general, will take longer now because you can't just go buy the BiS stuff after you get enough money. Good rares will become more beneficial and more valuable for those who want to trade. Finding those really good legendaries will be one of the end-game goals, and will actually be feasible with the new droprates. But you won't NEED them just to make progress like you do now.
