Guild Wars 2

Oh god, since D/D is so quishy quishy, can I reroute my points whenever I want if need be? Because as suggested, I may go for a S/P set, as it’s rather powerful. Opinions?

Hello, recently started playing Guild Wars, and as such, my characters do not have much money on them, and my thief is rather quishy, and I would like to know how to level up, and it is very hard to level up when your thief is rather quishy and dies to pretty much everything. I’m looking for a guide that will direct me, step by step, each area to train in, where, and all that I’ll need to know. I’m also looking to become a D/D build.

How do I set a weapon set to swap to?
I want to set D/D and P/D how do I do this?

How do I train in the beginning? I’m so bad. The thief is so squishy in the beginning ( as from what I’ve heard ) I’m getting… you know… the r worded.

This is the thief build that I’ve decided to base my thief around:

What’s your opinion of it? I’ve gotten the build from this video:

Go say hi
It is not in anyway, shape, or form my build.

What’s a WvW? I’m already lost. I might go with the S/P though? What’s the general opinion of it?

Hey guys!
So I just started out on this game ( the game is still downloading :/ ) and I decided that I wanted to go with a Dagger/Dagger thief ( I want it to be PvP orientated and be good at PvE as well, but more PvP focused ).
If you think that if another thief set is better, please list it down below
And I was wondering if someone would be kind enough to list a guide from 1-80 leveling guide and where to distribute my skills.
Also, a money guide would also be useful.

EDIT:
If this is in the wrong section, I apologize. I have no idea where this should be
And, please put it in easy-to-understand terms and don’t go all GW2 phrases on me. I really wouldn’t understand them.

Thanks in advance!
