Guild Wars 2

Hello,

So my toon is currently level 50 and I am wondering how much it’ll cost and how long it’ll take to get her to level 80, I know almost everything there is to the game already due to having other toon’s. I would like level 80 so I am stronger in dungeons and WvW etc.

For about 20 gold you can bring cooking, jewelcrafting and artificing to level 400, using the guides on http://www.gw2crafts.net/. Depending on how many materials you have, it is even going to be cheaper. This grants you about 21 levels. The other crafting disciplines are more expensive. They cost about 15+ gold each, so I would not recommend it. I guess it takes you about 2 hours to do this.
If you can afford this, go ahead. It is probably the fastest way to gain the remaining levels. But even through normal play, you can get to level 80 quite quickly (say 2-5 days, playing just a few hours each day). Since your goal is to become stronger in dungeons and WvW, it is probably best to use those for leveling up. You get some decent experience in WvW and dungeons, but you also get to know your class and the game modes itself better.

What does no hearts, top 5 hearts and all hearts mean?

You can buy many cooking ingredients with karma, which therefore saves you money. In order to buy them with karma, you need to have done the associated “heart quest” (those yellow hearts on the map). Hence, no hearts means that you have no access to any of those vendors and all hearts means that you got them all.
