Guild Wars 2

It has been nearly 3-4 months since I last played this game. I played hardcore int he first few months and now am trying to make a comeback. I feel overwhelmed can someone give me an update as to what I have missed, or would anyone want to fill me in ? I have 2 level 80 Char atm Last I remember ( Updates).

I feel as though I wont know whats going on when I log in. I want to get back into GW@ just need a bit of help and a push to get be back on.

Thanks in advance,
