Crafting is a double-edged sword; The problem with crafting in RPGs is that it devalues adventuring. My personal view on the matter is that loot should come from killing things, finding hidden treasure and completion of quests. Not combining cowskin with needle and thread to make [Best Boots in the Game] without ever having to leave town.
I want my good items to have a story more exicing than 'oh I just made that out of things I found on the floor'. Though I wouldn't mind if there was some way to change or shuffle stats around on a piece of gear you really like -- because the random loot generation in this game is a bit awful. I don't want int on my 'requires 14 strength' chestpiece, and it would be nice to have an option to somehow 'reforge' it to have better stats.
I totally agree, but the problem here is that I, for example, didn't use most uniques, not even the good ones, because by the time I got them, vendor items were usually better (and necessary), because the level differences are very, very big.
Which is why I'd love to see a hybrid... excessively good and interesting uniques which grow with the player level (the Eternal Armor is very, very well done!) and "upgrade your self made items when you progress", for example at level 5 you unlock the first + primary attribute point for your chest, at level 6 you unlock the first + civil ability point on your belt, etc...
Add transmogrification, a system with achievement-based vanity design options (across playthroughs) and special "crafting reward quests" and you're done.
However, killing a level 20 enemy everybody and his brother on the Internet is raving about how supposedly hard it is (it was not, btw...) and getting a meager level 18 item for your level 22 character doesn't work that well.
Oh, and the shopping @ level 22 was horrible... watched two episodes of ST:DIS on Netflix on my right screen while I waited for the vendors to restock on my left screen before I engaged the "oh so hard enemy" (seriously?), because there were almost no useful items. Which is why I finished my first playthrough 01:00, not 23:00...
I like crafting and customization. This could add very interesting theorycrafting as well (the irrational RNG for shop items and drops is not helpful in this regard - what is the reasoning behind +2 Finesse on a "requires 14 strength" chest piece?).
