#0 - you can edit your post to bypass the 1000 character limit. Other responses to follow as an example.
The only things that will make a harder experience is your skill with the class and the DF queue. The queue for any dps class will be longer so it will generally take longer to get into dungeons.
Class specific comments:
- Monk - attacks are highly position dependent. Generally considered one of the hardest dps classes to play well.
- Marauder - one of the tank classes. Good for DF but you will be expected to take the lead in all 4-person content.
- Summoner - there is a big distinction between summoner and arcanist, but more on that later. Arcanist is one of the best solo classes while outside of dungeons.
- Archer - very mobile and pretty easy. Limit break is healing, not damage. Also will be expected to know and use the bard songs for support post-30.
- Lancer/Rogue - I think these are the most played dps classes. Dragoon rotations can get very complex. Ninjas have more options with mudra combinations.
Generally just put all of your points into your main attribute. Arcanist can be the exception.
And yes, you can but an item from your grand company to reset your attribute points.
Bard - never played 11 but from what I hear, no. This bard is more support and less dps. Still fun to play though as you never need to stop moving.
Arcanist - So far you just have all the classes. When one of them gets to level 30 you can pick up a job. The jobs are the party-optimized versions of the classes and generally considered an upgrade. For almost all of the classes there is only 1 job available. The exception is Arcanist. The arcanist can pick up scholar (healing) and summoner (dps). This is why some arcanists split their attribute points between mind (scholar) and int (summoner). Currently black mage is preferred over summoner for the final coil of bahamut but that is the only end game issues I've seen. The summoner job is still contentious though because it isn't what some people feel it should be in terms of pet usage. Because of some of the arcanist abilities summoner can also act as support if needed.
Crafting can make a lot of money but to make the really high level stuff you will need to get all the crafting classes to 50. Most of those high level recipes also require drops, so farming is also viable.
I find crafting most useful for making stuff for myself and not having to buy it from the marketboard.
DUCK!
Summoner and bard because I like the support classes. Mainly summoner as I feel my dps is higher and I like having rez.
