LF Thieves Guild/Group
If you are looking to learn a thief in WvW, I would suggest roaming solo.
You will encounter a lot of stragglers along the way and initiate a fight with them. On such encounters you would learn the ins and outs of the class and the do whats and nots against different classes.
Also, it will help you in your map awareness as you will always have to try and avoid big zergs or trying to pick off the tail of it.
