It works both ways
Every MW game I played the Mentors Ring, Amulet of Shadows, Boots of Blinding Speed etc were waiting to be found in exactly the same place as the last game

i understand your point completely. however, it highlights what gets me so pissed off in the first place: a lack of gaming advancement.
why can't we have the mentor's ring having a new random location for every new game with the associated vague reference to it's location?
why can't we have white woe uniqueness but placed randomly at the start of every new game?
the only answer i can ever counterpoint myself with, lol, is that i'm not a programmer and have no clue.
don't even get me started at the utter lack of a.i. advancement in video games. or, the fact that gamesas can't develop a game that remains difficult throughout.
or, every game having depth of customization and options, dialogue and meaningful quests.
