1)can u make other characters like in ffxi?if so is it free?
As many as you like, no charge. You get to pick your server, too. None of that random placement crap.
2)is the character creation good?please give details!!!!
Yeah, I guess. You choose your faction, race, and class, and can customize your look (though I thought this aspect was somewhat limited).
3)does armor and weapons have repeatible looks?
For the most part, aside from epic gear.
4)can u craft?
Yes.
5)whats the battle style like?
You've got a hotbar of actions. You target a monster to attack, or target a player to heal, etc. General MMO fair.
6)is the world huge like FFXI or is it bigger or not as big?
It's really hard to compare MMO world sizes because they're all really huge if they're worth their weight. WoW is big, yes. You'll realize just how big when you ride a griffon anywhere.
7)can u make ur own linkshells or what ever you call them guilds maybe?
Guilds, yes. Linkshells is such a lame name.
8)hows the community?
Pretty excellent, actually. Friendly and fun.
9)how much a month?
$14.99. The perk is that you aren't charged for extra characters, which is one of the dumbest ideas ever.
10)are there diffrent servers if so how many?
Yes, like a bajillion. I dunno, I'd guesstimate around 50 active, both PvP and normal.
11)can u switch jobs in the game?
Sort of.
You get a main class, which is the archetype for your character. You can buy skills as you level up at profession trainers, and once you hit level 10, the Talents tree is available. Every level you get a talent point to spend somewhere in one of your available trait trees, but you won't end enough talent points by 60 to be able to be a jack of all trades - you'll go for a specific build. Of course, you can respec, which costs lots of money, but allows you to redistribute points in your talent tree. So you can sort of reroll your character.

As for professions (tradeskills), you can learn two of them, but if you decide you want to go for another profession, you can unlearn one of them. Like if you go for engineering and herbalism, but decide that herbalism is pointless in tradeskilling with engineering, you can unlearn it to get mining or something. But professions!=class. They're just tradeskills for crafting.

Hopefully this helps out some.
