So I'm cruising through the temporary data and looking at all the possible items and it's obvious that the level 10 blacksmith gear with 6 random stats will be amazing come endgame, albeit a gamble to get the right combination of 6 stats. That's where the auction houses come in but that's another story. The point is that crafted level 60 gear will be easy to obtain and powerful. I imagine we'll be wearing pieces from this set for a while until we manage to replace it with drops from inferno (except possibly pieces with Magic Find % on them, I can see those being very useful but again that's another thread)
I threw together a rough and dirty compilation of the best inferno-level crafted gear for all classes, then did a quick forum search and found some screenshots from the beta client of the sets (all except the wizard one). These items will be made by salvaging inferno level rares and magic items/weapons as well as a larger quantity of salvaging materials obtained from salvaging any item.
I'll do some more searching tonight to try to find the missing set.
This isn't new info by any means, but I found it interesting and thought I'd share: This is what the best crafted gear in the game is going to look like at level 60 in Diablo 3 XD
First off this is what the gear will look like for each class (incoming MS Paint montage I made from info on the official diablo website):
Here are some screenshots I found (source: diablofans forum member drakefish):
I'm pretty sure the screenshots are of the "create a class" preview in the beta client. Here is the original post with more screenshots of random gear
Edit** Of course you have to take into consideration the plethora of different dyes available. including vanishing dye that'll let you hide pieces of your armor! This game is going to have so much more customization than d2!
