Guild Wars 2

Its been a few months since i last played and I was wondering what profession and build to play, I was thinking some sort of hard hitting mobile artillery style maybe the a DOT ability (sort of like SWTOR mercancy/commando Pyrotech/assault spec). If there is anything close, then please tell me as I want to come back.

Maybe a necro? Or engineer? Both of those are the strongest condition(DoT) classes. For specific builds youll have to ask on the profession forums

You definitely sound like you want to play Engineer.

If you want a good answer to that, you need to give more info.

1) What game mode? PvE, WvW Zerg, Roaming, sPvP?
2) What level you are aiming for : Do you want to play casual with an easy build or go more in deep with a good build.

grenade engi with condition build probably.

Game mode I want to expeance it all and i want to play semi serious so casual but can up my game when needs be, and btw I hate granades
