Guild Wars 2

I am currently a level 42 thief and I am wondering if their is a good thief player or someone who overall knows the game well that can help me get better/ learn the profession.

to actually learn all about the profession you need to first get level 80 (what should be fast anyway), afterwards feel free to get in touch.

it might help to know your server just in case you want to personally go through things without having to join party, lfg, etc

have you tried to go to metabattle? or watch any of the youtube vids if any are posted under the thief profession?
