I honesty like the battle system in FFXI. It takes getting used to after playing all of the original FF's, and even though it automaticly attacks, you cant tell me you're not scrambling to shoot off your next spell or wait for your TP to hit 100% and fire off a weapon skill to save you from behing killed right at the last moment. Its different, but it still has a level of intensity to it. And it'll be nice to see the monsters for a change.
The one thing that annoyed me in every Final Fantasy: Having enemies pop up randomly when you're trying to go somewhere or do some quest. You can now choose when you want to fight and when you want to run, unless they put Goblins and Quadavs in the game...bastards.
