I'll grant that "exactly the same" may have been an overstatement, but the fact is they're actually very, very similar, going purely on your description of the Tome.
You can't get items from completing LOTRO "achievements" (as far as I can recall) nor completely new abilities, but you can get traits which can add additional effects to existing abilities, plus you get XP when you complete them, titles for some, too.

You describe exploring out of the way places and getting a Tome entry for that. LOTRO has exploration entries like that.
You describe killing monsters and getting monster kill unlocks. LOTRO has that.
Quest completes? LOTRO has that.
LOTRO doesn't start you off with an entry saying "Kill 10 goblins". But once you kill a goblin, you can see that you'll get a title for doing it. And then a trait if you kill 100. You don't walk up to a hobbit and ask for the quest, it's automatic... just like you're saying WAR's is.

Maybe WAR has a lot more of them, or there's a better variety of rewards or what have you, but it's still not "unlike anything seen in other MMO titles." It's what LOTRO has been doing for a good long while now.
That is not a bad thing, but it really should have been acknowledged and not talked about like this was a stunning revolution in MMO gaming. It simply isn't.
