xbow got great damage (with crits) and good range. just get the xbow for now..and try to get either cleric (for survivability), bard (speed), warlock (pvp) later on.
Its kind of hard to choose what you want, especially if you are new to the game. Anything Chinese requires a shit-ton of sp. Get used to it, to be great, you need to put in the time. Euro's, however, are rather easy on grinding/sp. You have two tree's and although there are tons of skills in the trees, rarely does anyone max them all out. You can easily zero gap to the top, and spend a week or two at the end sp farming for the next gap increase. Damage on the Euro side is much higher as well, but it comes with a price. Generally, Euro classes sacrifice health for power, and that is their weakness. As it is, most pvp comes down to who hits first, and who has better gear/buffs.
In the end, your decision will come to personal preference. Euro = short grind time and power - health. Chinese = long grind time, pretty strong, and hp out the ass. Each has it's perks, and both have flaws. Have fun with the decision. xP
The Crossbow. It can KD, KB, and Crit like crazy. Although it can't compare with Daggers for Crits, its still pretty freaking awesome. It also has the longest range of any weapon
