I chose this class, what should I be doing
Hey! Posting is locked for everyone that doesnt have the game to prevent offensive spamming I guess… You should be a tad more specific with the question, how familiar are you with gw2? Do you have the expansion? What do you want to do in gw2 really (what sort of player are you?)?
Assuming you just started a new character: walk around and do any events that pop up nearby, they show up with a description on the right side of your screen. Otherwise just do heart quests and hero points. Once you have a few silver, head back to starting point and into the nearby city, and buy so you have 1-2 daggers, 1 scepter, 1 staff (trading post or weapons merchant), 3-4 8-slot bags (trading post), so you can try out different weapons. Hero points unlock skills, events level you up. At level 10 you get the main story quests.
