But if loot isn't part of the game, then why the RNG loot that falls like rain? Part of developing a character is obtaining better loot and gear, and previous Divinity games did indeed have unique item sets (Blood Echelon, Aleroth Archmage, Hunter's, Scorpion's, Dragon Wizard, etc).

I'm just saying that the loot and craft system can be expanded and improved on, devoted crafters should be able to craft unique items, like the Sword of Planets and the Buffalo Sabre already in game. Why are there no staff, dagger, bow, spear, 2handed equivalents? Why aren't there any unique armor? Most old school RPGs had handplaced non-RNG gear.
