Thief is nice mate, i have a level 30 which is my main, but I can say one thing on Piken Square due to us being underdogs it's very hard to get stuck into the action unless you use pistols, I also find you need to have a few stealth skills so you can duck in and out of fights quickly, all in all GW2 is fun, hoping they sort out the ranged classes, as at the mo it's very range centric apart from tanks who just seem to pile in and don't die
but on the plus when I do get stuck in most times they lose ;-) and that's using daggers hehe
