I just seem to leave over boredom
Leveling other jobs is a drag for me, end up just waiting on DF.
Crafting jobs I just don't feel have any real impact, I can get more gil from just running dailies.
Story quests are awesome! They just are over so fast...time between updates are long
Regular quests are not very fun...
Not enough non combat activities to do...Gold Saucer, mini-games, farming, whatever. Game needs more content besides just combat.
I really love this game... best since FFXI, but something is missing for me. I am glad other people enjoy just as it is, I just start to feel very bored not long after content patches.
I'm sure after some time FFXIV:ARR will have too much content to handle just at the moment for me leveling other jobs and running same dungeons are not content.
I hope they concentrate on story mission most of all and Eorzea as a whole and not so much endgame min maxing like so many other MMOs do that wanna be the next raiding thing.
