Guild Wars 2

Welcome to Guild wars.
http://en.gw2skills.net and http://wiki.guildwars2.com have tons of information. Start with the first for an easy to read list of weapon skills and utility abilities.

A thief in Guildwars isn’t like one in WoW or other games. You don’t go around always in stealth, its more of a mid-fight mechanic.

Here is what to do from someone who just finished leveling a thief solo.
Starting around level 7 you can equip two weapon sets and switch between them on the fly with the ~ key. For solo pve leveling the Sword and Pistol (S/P) combo can not be beat. The number 5 key gives you a 4 second blind field around you, so any mobs right there can’t hit you for 4 seconds. The number 2 skill lets you quickly move up to a bad guy but also hitting it again lets you quickly move back. More importantly however, is every time you use the “move back” part you clear a negative condition on you. Bleeding? Just hit 2 twice. Even works out of combat. The number 3 attack will interrupt an attack from a bad guy and then do a fast three swing attack that not only will hit up to 3 guys, but also makes you dodge during it so you can’t be hit. For your utility skills go with the signets. The healing signet plus number 3 attack with s/p will fill your health back up to almost full from really low. Then there are signets for power, and precision, and then I switch between the signet that gives you an extra initiative every 10 seconds and the one that lets you run faster.
For your secondary weapons you can either carry a ShortBow (sb) or Pistol Pistol(p/p). Shortbow is good for groups of 4-5 but takes some learning. P/P is single target but very strong. Use skill 3 and then start it again before it ends to keep the extra damage stacking up. From a full initiative bar you can chain 3, skill 3s. Plus it looks cool.
Every 10 levels go to the Auction house and buy new weapons and armor. Go for items that have +power and +precision. Power makes you hit harder and precision makes you have critical hits (more damage than normal) more.

Feel free to add me as a friend in game and ask me questions when you get confused.

oh and here is a great link just filled with tips http://wiki.guildwars2.com/wiki/Tips I wish I had known some of these when I first started. A couple of the tips are outdated, but mainly its a great amount of info.

I recommend trying all weapon sets, by the time you reach 80, you’ll have good understanding of what weapon is best for each engagement in pve, wvw or pvp.
