What a lot of people in this thread are seriously missing is that this game does not fit the usual Western/Freemium paradigm of the ‘Themepark MMO’.
This is not an entirely quest oriented, chug-along-the-traintracks type of game, it borrows elements from these kinds of games but the primary focus, and leveling method, stems more from ‘Sandbox’ styled games like Ultima Online and Ragnarok Online, where exploration, grinding, and community are the focus and mainstays of leveling, not questing and a series of ‘appropriate’ zones stacked along the railroad tracks.
You simply aren’t going to solo through all the content to get to endgame content(a common pitfall in MMOs emulating the WoW Formula), that isn’t how this type of system works.
You find leveling parties, you hang out in farmable areas, you work with your guild/friends/the community to level over time. This isn’t meant to instantly gratify you, blah blah something about the journey not the destination.
This is not a WoW-Killer Themepark MMO, this is a niche game. If this kind of playstyle isn’t for you, then you may be better off finding another game to play.
EDIT: Another thing to keep in mind is that everyone is tackling this game blind, and a majority of quests, especially repeatable ones, are not implemented. The grind may seem insurmountable now, but after release routes, guides, and effecient methods of leveling will severely cut down on the time and effort it takes to level. A good player with proper knowledge and the full range of content will likely level much, much faster than we are now even with the CBT EXP bonuses.
