Final Fantasy has always been it's own type of game and each one has stood out for specific reasons. The main reason it has always made word to millions even if the game is terrible (FF14) is it's world full of content! Final Fantasy has a huge history of games with riches of content that could be tapped into for ff14. Things that I would love to see within the game:
-Mounts: Doesn't have to be anything new, just create different colors or color patterns on Chocobos and allow mounts.
-Like the old days multiple AI on team that you can control (Example: Guildwars Heros or Mercenary system). This would allow the game to have a faster pace to it because you need to control more than one Character. Like quests, just add a control of difficulty to balance this.
-Something that is staring to becoming a common thing for Games is player made contents. If FF14 made guide lines for quests which allowed players reward others with ingame content (Crafted items, Gil) to find items or contents that they need. While the player that posted the quest is logged of, another player can attempt the quest complete it. When player (Posted Quest) logs back on, he see's that quest was completed and he has what he needs (Instead of farming or grinding all the time).
I have many other Ideas that I'll post later but would like to here feed back on these.


Thanks, play safe!
