I decided to point out the obvious.
By the time I hit 25 in FFXI, I had survived the Buburimu deathrun, survived the Jeuno deathrun, got a chocobo license, got an airship pass to a far off realm, got a subjob, and got myself to Rank 3 with Sandy. By the time I hit 25 in WoW, I'd survived the Menethil deathrun, got Cat Form, survived the Bear and retarded Aquatic Form quests, and endured my first ganking in Raven Hill Cementary. By the time I hit 25 in Aion, I'd gotten my wings, gotten my first stigma, finished all the campaign quests in Altgard, and got my license to enter the Abyss. By the time I hit 25 in Rift, I'd purchased a mount, unlocked all of my extra souls for the Warrior class, completed major storyline questchains in two zones, and fended off a dozen invasions from all angles.
So I'm closing in on 25 in FFXIV, and I'm still in Thanalan, doing leves, because finding good grinding spots feels like I'm playing darts while blindfolded. I'm almost 25, I've opened up and fiddled with every class, I've done a few of these important quests in LL, but I'm still wandering around one of the four entirely too large zones looking for things to kill (that are 7-9 levels above me, because they actually offer decent exp). I'm wandering around because what else am I supposed to do when I finish all my leves? Play on an alt? Grind some DoH/DoL classes for a bit? That's neat and all, and I do enjoy that a great deal, but I'm not feeling a sense of progression during any of this. This isn't even sandbox type gameplay -- there's no sand in the box; it's just an IOU with a promise of sand some time later.
The zones are so large that nearly all of its real estate is wasted (and their size makes the copypasta aspects of it very, very blatant). Camps could be great quest/group hubs, but they're not, because you can't get leves there, and behests are mindless zergfests. Mob level spikes are the strangest of all, for me -- Mor Dhona has a section teeming with level 30-33s that would be perfect for grinding on, but to get there, I'd have to brave areas with aggressive 40-70s [i](via Coerthas), or aggressive 50-55s in narrow corridors that make sneaking past nearly impossible (Black Shroud). "That means it's a high level only area!" Of course, but the same strange phenomena happens in all the other zones -- all four of them.
I'm not asking for an on-rails themepark wonderland, but FFXIV lacks pretty much anything in the way of definition. I'm still leveling my little Miqo'te because I'm still largely enjoying the act of leveling, but it really feels like I'm on a treadmill. The carrot on the stick mentality may not be the best thing the MMO genre has going for it, but FFXIV has no carrot to speak of. Here's hoping Yoshi-P and co can bioengineer one before long. XD
