Tone is an extremely subjective assessment, one that is honestly hard to take seriously as a critique of a sprawling MMO. LOTR itself varies widely in tone, and trying to compare the tone of a 60 year old novel with that of a 6 year old video game is specious, to say the least.
You also do a terrible job of sticking to the subject at hand. The subject is lore, and specifically perceived contradictions to who and what was where and when, not tone. Nice try, though.
