I just bought the game and will pick it up next week. I just had a quick question that I would like to ask to this community.
Which job should I choose? I can't decide if I should go for a Dark Knight or a Dragoon What's better for a beginner and overall more enjoyable in your opinion?
I heard Dragoons are kinda underpowered and that Dark Knights are quite complex and have a high learning curve. Don't know if you agree with these statements.
You can level every job on one character, and you can instantly change between them freely (unless you're in a dungeon or other duty). As has already been said, you need to get into the expansion area to unlock Dark Knight and that will take a while if you're starting from scratch.
I'd say start the game as lancer (upgrades to dragoon) and see how you feel about it at level 50. Level 50 is the cap for pre-expac FFXIV and it's also the point where the jobs really come together, so that's essentially the point where you truly get a feel for a job. (Unless you're a bard, but that's another topic.)
One thing to keep in mind is that dragoon and dark knight have different roles: dragoon is a DPS class, while dark knight is a tank class. If you're not that fond of lancer/dragoon, I'd suggest trying gladiator (also a tank class) for a bit. It upgrades to Paladin, and has some cross-class skills you'll want to pick up for Dark Knight. But most importantly, you can use it to learn how to tank in FFXIV, and the basics of the job isn't too different from Dark Knight while you're levelling. Marauder (upgrades to warrior) is fine too, but I think Dark Knight has more in common with Paladin than it does with Warrior.
Either way, once you get to the expansion area, you can jump into Dark Knight at level 30, and see how you feel about it without losing your progress on Dragoon. You'll also get a solid experience boost for having another job at a higher level. Or maybe you'll decide you hate them both and level summoner or something instead! There's plenty of different things to try out.
