Already pre-ordered it. I played through the various beta phases and thoroughly enjoyed the game. There's a wealth of content right from the start that just isn't present in MMOs. Almost immediately - within the first few levels of play - you'll have access to all kinds of quests, such as quests from your class guild or main plot quests along with the typical quests from NPCs, "leives", which are individual battle/events for solo players with unique conditions for victory, dungeons to conquer, your "hunting log" which awards bonuses for hunting down specific monsters, and more.
Grinding mobs is totally unnecessary, but if you decide to do it anyway, even that has been spiced up a little; kill two monsters of equal or higher level than you and a timer starts. Each monster you kill while adds a little time to the timer and you gain bonus exp for each successive kill.
I would honestly recommend the game to anyone, even those unfamiliar with MMOs. It's so welcoming and easy to jump into and introduces you to new things gradually enough that you won't forget what it taught you, but not so slowly that you get bored.
