Because full rewards moves the game forward to the 6th age, certainly events need to of happened. I wonder how the quest looks/ends to someone who has done no quests whatsoever. Exactly the same, the quests just get you the title, slayer dungeon and '6th age circuit' (which is our indicator of the year/age having moved on) from what people have said anyways. Though logic-wise it would be very problematic. 1) Juna recognising you - How's that without ToG? 2) The Crux Eqal - Again how without right quests? 3) Sliske - Treating you like you met before, again how without rotm 4) Azzandra, Enhkara, Anthankos, Wahisitel and Char - how without the right quests to free them/reveal them? All in all it really seems like aside from 140cmb the base quest should really require ROTM + Firemaker's Curse + ToG (don;t think it appears in rotm reqs) just to make all the npcs make sense. It's simple really, the other quests are in the past, so when you do TWW, it's after you've already done everything else, even if you haven't done anything else.
