There's a difference between "kill dragon, get his hoard" and "kill dragon, get an item drop that's specifically tailered to suit your character cause we can't have a drop that might be more suitable for other types of builds" though.
Yep, also the "dragon hoard" was a list of numerous items to which the GM rolled a dice to see what items were present. Though these are the little things people forget about gaming systems.
Can you imagine how the loot tables would be in the back of the module if the games were all about this proclaimed "tailored" focus? Instead of a D-100 roll out of a table of items, it would be a decision tree of: Is party member a warrior (yes/no), is the warrior a single handed or dual wielding (yes/no), is the warriors alignment (good/evil/etc....), is the warriors... etc.. etc...
