Guild Wars 2

I’ve been trying all different class but i seem to can’t choose my main.My goal for gw2 is to make a legendary for my main.
I really like playing pvp and a bit of pve, can u guys recommend some the goods and bads of each class. Thanks

So I’ve been playing different classes but Thief was the best so far so I’ve decided to make Thief my main. I’ve been just opening maps and I’m about halfway. I’m now lv45 and I need help about what to do after I hit lv80 and where to get the gears because my other characters I just buy it off the TP and I dont want to spend like 50g for the gears and weapons. Pls help
