A couple of questions from a new player
The best advice I can give for a quick level is crafting, if you have some spare cash buy gems, convert to gold in the gem store currency exchange then get crafting!, costs about 100 to 150 gold per levelling guide I think, ten ton hammer do good crafting guides, just type in Google gw2 ( insert crafting name, armour smith or whatever) guide, it gives about 8 levels per 0 to 400 crafting. That’s how I’ve been levelling my alts that I can’t be bothered to do hearts with hope that helps.
I prefer map completion, myself. The personal story can help, too. Everything in the open world gives xp, exploring new zones, gathering, rezzing players… If you see a dynamic event, do it, especially if you haven’t done the nearby hearts – that’ll give you the most xp. Buy cheap food consumables on the trading post and keep their buffs on.
I don’t play necro, but here’s a good site for build recommendations: http://metabattle.com/wiki/MetaBattle_Wiki
in fact, we’re going to put the goons to sleep.
Meanwhile – we dig.
well if you like PVP, then just PVP your way to 80, you get tomes of knowledge that gives u a level for each one, also just logging in daily will give you 10+ tomes per month.
ive leveled 8 toons from 1-80 using just tomes, its simply the fastest way if you enjoy pvp.
as for necro build in pvp, u can run minion master, its pretty forgiving.
