Stick with WoW, Andy. If you're still 37 like your signature suggests then you've still yet to experience even a 3rd of the game. You've still got your blue mount quest coming up with your crappy prot spec paladin. Go holy! You healz! Get to 58, go to Outlands and some of the most visually stunning zones in the game as of yet. The people in Nagrand may suck, but the region is just wonderful! Hellfire Peninsula, and Zangarmarsh aren't that bad either. You've got a long way to go still, but really. Stick with it. You've got a lot of the fun still ahead of you as of yet.
On the note of FFXI, you've experienced most of it. Sure, you didn't beat Maat. He's overrated. Sure, you've probably never been to sea. Biggest headache ever. You've probably experienced some portions of sky with the lesser gods, annoying as all hell. Maybe you've even had a chance to sing a few of your songs at a Kirin fight. Not that cool.
Trust me guy, at 60 you'll be fighting some fun Elite mobs that have more HP than Kirin. What does he have? 40k, or something like that? Yeah, about that. Most of all, you get to solo them! What does that say about Kirin? Exactly, he's a final fantasy mob.
Sure, if this didn't convince you to stick with WoW then go back to FFXI. Go back to the constant farming for gear that costs so much it's really not even worth it. Go back to the mindless grinding, and skillchaining. Singing your songs to people that beg you for this, and that. Then, if you beat Maat. Go pull your taru head off in Caedarva Mire. People quit FFXI due to several different reasons. The majority of those that quit do so because the game just stops being fun, but then they begin to miss it and wonder why they quit in the first place.
Let me blow this horn; It's because you couldn't beat maat, and because I kept bugging you to come EXP when you couldn't get any, and..the game stopped being fun.
PS; Stick with WoW, move to my server, and i'll help you.(Not really.)
