Several questions from a newbie

[Shibi]

1- Im not an MMO lover but I am playing this game because I am a big FF fan and I have read several times that it has the best story in the whole saga, but I have also read that it gets interesting in the first or second exp, is it right? So far, the missions are "chat with this person", "get 3 flowers in that garden", "slay that easy monster"...also there are missions where it seems that they make you move from one point to another just to spend time. When does it get better? I just want an amazing story

Watch for this head icon (looks like a meteor) as they are the Main Story Quests (MSQ)and do these quests only. Ignore the ones that are like as they are side quests, for your second run through.

If you do this you will only have about 150 medium-boring quests to get through to get to the meat of the story. These 150 or so are laying a foundation for the story, so while you will feel like an intern being given a menial task, that sets the scene for the later story.

2-Regarding difficult, so far all misions and raids are really easy, when do it get difficult? I have seen dungeons in the map but when I get there, I cannot enter.

The game is teaching you basics in the lower levels, so yes, it's simple. If you follow the MSQ meteor icons you unlock your first dungeon around level 15.

3-Regarding autoatacks: I have first to click on an enemie so my pj starts atacking him. Is it possible that my pj atacks automatically to the closest enemy? Because some times there are several allies and enemies so if I misclick, my character do no action nor atack

Not sure what a PJ is... sorry. Most people target with the <TAB> key to select the enemy they wish to attack, then fire off the spells in a set sequence.

5-I selected the monk but later I read that its considerent within the worst jobs. Which are the most popular or fun to play jobs? If I play DK, it starts with level 30, but the missions would be level 50 right?

I like sage and reaper, which are jobs unlocked at level 70, and Gun Breaker, which is unlocked at level 60. Maurauder is pretty fun too if you like big axes and slower gameplay - but as it's a tank you will be leading other people through dungeons.

There is also a third type of icon with a blue (+) in the bubble, which indicates that it unlocks some kind of game feature.
