Guild Wars 2

Hey there, not sure if this is the best section to file this under, but I’ve been gone since may and have recently got back into GW2. I’ve noticed that an awful lot has changed and it’s rather overwhelming right now, if you could help by consolidating everything into a few paragraphs, or even linking to the most informative, but concise material you can find would be much appreciated. I currently live a very busy lifestyle and if I were to read over everything there is just to find the few nuggets of information I need I’d have no time to actually play GW2.

My main is a necromancer and I’m used to playing it as a condition build. I’ve already re-jiggered my traits a little to help with that. I’ll break my main needs down into a few questions, for easy answering.

1) What changes have been made to the necromancer profession; is there anything I should change? I mainly play PVE, dungeons mostly.

2) Is there new equipment or items in game that make a significant change to the way the game is played, if so, what are they.
2.5)Should I be aiming to get any new equipment myself, currently I’m playing scept-dag + staff, with nightmare armor.

3) Are there new areas, quests or challanges? If so, what are the major ones? Do you have any personal recommendations?

4) Have the game mechanics changed in any significant way? If so, how?

5) Is there anything else you should inform me of? Is there anything else I should be doing?

I’ve already done a good few google searches and mostly found pages of content, which would take me hours, if not days to read, I understand there have been an awful lot of changes, I only really want to know about the ones that will affect me significantly, I’m happy to learn about the other ones as I play.
