I think this game beats WoW as far as storytelling goes. And when I say WoW, I mean everything beyond Vanilla. Vanilla was good because everything still made sense, storywise.
However...
At no point in WoW did I actually FEEL like a hero. I was a "champion" in WoW's story, but the real heroes were the renowned NPCs from games past (WC 1, WC 2, WC 3). We got a "Hero Class," but it stopped feeling heroic when people (PvPers, lol) cried nerf and the Death Knight got nerfed to oblivion.
In FF14, I feel like a true hero. Not THE true hero, just A true hero, because I have you tanks and DPS to protect me when the heat gets turned up =3. Still, there's one thing that bothers me, if ever slightly...
*Heavensward spoiler ahead*
At the time we fight Ilberd during Raubahn's rescue, we're technically godslayers, and we're recognized as such. How, then, is Ilberd able to withstand our assault for so long, beat us silly, and make it out alive? He's just a man!
