Guild Wars 2

I started playing at launch and got a guardian to lvl 80. I tried more than pnce to do a dungeon with a group and it never seemed to work.

In CM cadices manor I think it is called. I never understood why my character was their, I got a mail saying your invited to CM. And once we started playing the dungeon I had no idea what our goal was.

It was the same thing for another dungeon. Can’t remember what the name of that one was.

but could some one give me a quick run through of the different dungeons and such? Like also what is the differences between exploration mode and the other mode?
Are there like main bosses in the dungeons?
Is there special loot in the dungeons?

The wiki gives a good explanation. Your objectives are on the top right and indicators/markers should be on your map.

Dungeons have 2 parts, story and explorable. Story goes over the dungeon and ties into personal story. It’s like an intro section. You can’t start explorable mode until you have done story, although if someone else is opening the dungeon they can bring you in even if you haven’t finished story mode. Explorable gives tokens for end-game gear and is full of combat, etc.

The most important thing when doing a first dungeon is to tell your party members you’ve never done it before. Most people are perfectly willing to help a new person, but you need to say that at the beginning or they won’t know.
