Guild Wars 2

Hey, I just made a thief and used my bday present.. im currently now lvl 23-25… I didnt 100% any place yet but lions arch. I really have trouble levelling all the time. It took me a while to get both my mesmer and guardian to 80. Can someone just help me get levels fast?

Also, I need a good thief build. I plan on using him mostly for WvW and would like to sustain but also do tons of damage. A good build would be nice.

Thanks for all your help

For leveling just use Sw/P. lets mobs sit in your blind field and auto with sword. Have the thief forum help with whatever else you need.
