as a new player, I'm going to have to disagree with some of them answers
I have found that as a new guy (I am lvl 17 in most of my classes) that most people with a bunch of 50's next to their class have lost touch with what it takes to actually start this game from scratch. for example: a lvl 14 Glad weapon sell on the market for 100,000 + now I don't know about the rest of you, but at lvl 14 100K was 1/3 of my total bank! And I got there slow, you can burn to 14 in a day. But I could make the item for 200 gil. I'm sure that will vary from server to server. If you like crafting, invest in it.
3. This game is cash (gil) hungry, The inflation rate on gear is just ridiculous, Maybe once you have friends with deep pockets you will be OK but starting .. doing some Combat Leve's , you are going to be hurting for gear very fast. Almost nothing in the game drops gear and quest give so little gear its almost non-existent at the lower levels. Once you fight your way though the worst market system in the history of MMo's you will quickly discover you don't have enough money to buy anything. I found that by crafting you can make a lot of that gear you cant buy. Crafting at the starting levels cost nothing to level up and since the crafting change is actually easy. I suggest a weaver or blacksmith to make most your early armor and weapons. The you can feel free to join in the rampant over priced marked and propagate the problem to the next generation of players.
4. I have to agree that the Conj is a good even class, heals buffs AoE damage, the works. Do that and a damage type that you enjoy playing; I went lancer, but I like Spears
6. On my server 2 cities are empty and we all hang in Ul'Dah. The only bad part about not hanging there is the other cities markets are empty, you want some pelts? sorry go to Ul'Dah. You want some woods? Go to Ul'Dah.
lastly doing the disp of the lands is a great idea, just leveling up do you can harvest Dyes is a great source of income: And I find that raw resources sell for a highly inflated rate no matter what level that are. (really people.. 4000 gil for maple)
Just my 2 gil bro,
