Something else, in The Secret World, which is also quest-leveling based, there are these types called "Investigative Quests" where you solve mysteries and puzzles, sometimes literally researching things on the internet to solve them. SO Neat! ARR would be a great place for quest leveling like that (the "GC Midlander" thread being a great example of why^ ^). The point being, its all about how they do it, right? Quest-based leveling could be really fun and painless while still being challenging. Besides, theres always monsters hanging around...easy enough to find some brainless grinding, with or with out quests.
