Well, I'm not really for the item system in general, but putting things like poorly crafted will just be screwed up, maybe instead add random bonuses to armour depending on what style of build crafted them in the first place, I hardly think that randomised items are an issue here, all you need is a bit of motivation, or an auto-scripting program.
Or we could think up "dynamic" items and have upgrades which would be removable. As one of the GMs/Devs said (not sure which), the 3rd tier gear will go about blueprints, maybe also be able to find blueprints for special armour and weapon upgrades? It would take some time to make the items, but would add so much more individualism. Also, maybe 2 Upgrades per armour, or one if it will clutter up the fixboy too much...
For example (Note: this is based around the combat armour):
Lightened: -5%DR, -25% Mass, (+5% Movement Speed)
Integrated Small Arms Targeting System (Or something shorter, haha, ISATS, cool shortening...): +10% SG, +10 One Handed Weapon Aim Bonus
Cybernetic Visor: +20% Two Handed Weapons, +5% EW
Thickened: +7%DR, +50% Mass (-20% Movement Speed)
Integrated Exoskeleton: +2 Strength, +5% DR (+10% if Move Speed is Reduced), +1 DT (+2 if Movement Speed Is reduced), +10 BG, +10% Two Handed Guns Aim Bonus, -1 Agi, +200% Mass, -10% In all skills (-55% Movement Speed)
I have many more thoughts like this...
