Fast Leveling? 1-80.
probably impossible.
However if you want to make leveling less boring you’re not tied to one activity.
If you don’t want to do any zones, a good idea is to log in to a low level character to do the dailies and then log into your normal level 80. Did this lazy leveling with my warrior up to a point. It takes really long this one, but you put in close to no effort.
You can switch between doing zones, map boss events, WvW and when you hit level 45 – dungeons.
There are also low level areas you can grind. There are a few spots that I go grind when I get really bored. Basically your looking for an area (not a zone, just a small piece of a map) where the foes are tightly packed. I have a few areas in the starter areas then the 35/45 areas and then some in the two 80 areas. You generally want to be a good few levels above your target foes. I would suggest looking for an area with bandits, skritt or dredge or something that drops loot bags. This will help make a little extra money from selling the mats from the bags or you can use the mats to craft your way up a few levels every now and again. Also, if you attempt this, you may want to use some Magic Find gear, after you’ve killed a few hundred foes, you really start to notice the difference.
I know its grind (and I really hate grind) but you can make a game of it or what ever. I usually try to see how mant foes I can agro and kill at once.
