From my MMO experience, I would venture to say that the FFXI community had the largest contingent of players which I would consider "hardcore". Very knowledgeable, dedicated, ravenous players that would tear through and dissect any new content / new boss / new level cap / merit point system that SE could throw at them (except for AV of course) . . . In FFXI I felt that SE always underestimated how insanely dedicated this community really is. They would release these mini-xpacs that they thought were jam packed with weeks worth of content and the community would complete the content inside of 24 hours (on multiple toons).
From my experience, these were the players who were the least happy while playing FFXI. The point of any real MMORPG is not to "beat the game," as these people act like. It's to explore the game, accomplishing things as you go, and enjoying several different aspects of the game. Also, the "mini-xpacs" didn't really have "content." There was a short storyline for the first three. A very few did complete that within a day or two. Most people did take weeks or even months to complete the final fights. The non-mini expansions mostly took a lot longer. I'm sure there were exceptions, but again: If you completed everything as fast as possible, you had the wrong purpose in mind for playing an MMORPG.
I knew at least one person while playing FFXI who joined an "end-game" LS for FFXIV before beta even started. Most of us who knew of this just laughed and shook our heads at the absurdity of that.
Here in FFXIV, I'm seeing a similar level of dedication. On my server, a core group of my LS mates are all around Rank 27-28 in their main adventuring jobs. Unless the leveling curve or fatigue system catches up to them, or unless there's some kind of idiotic level cap system in which you have to perform a series of quests and fight Maat again to level up, or unless there is some other artificial barriers in place to impede their progress, I foresee this group hitting max level inside of two (2) weeks.
I honestly don't think you will be able to hit Rank
50 within two weeks; physical level 50 is possible. The surplus system will likely catch up to you. Even if you do, you will have a very 1-dimensional character that's not really ready for "end-game" content. You need the abilities from other classes to at least give you options. And, there may not be gear for those levels. If you do nothing but level straight to 50, you won't be making your own gear, and you won't have the gil to buy the gear. The highest level gear I've seen so far is level 25-30, and each piece is going for around 150-300K each. And I've seen that in maybe 2-3 bazaars/retainers. So, people trying to reach the cap within two weeks, I predict, will be quitting before their free trial is up.
It's not the destination
FFXIV: Luthien Tinuviel, Elezen Female, Balmug (And will re-roll on a new server in August)
FFXI: Luthian, Elvaan Female, Bismarck (originally Luthien on Seraph):
85RDM | 80WAR | 76DRG
I've always been of the opinion that Warrior was the Swiss Army Knife of Vana'diel.
