I have just returned to GW after a break of 2.5 years or so

I have all the games except for Eye of the North and 3 or 4 lvl 20 chars.
So my question is (just brief details required) is what has changed in the last couple of years.
I'm assuming there is still no AH, the game is still as fun as it was and that I have no idea where everyone is hiding!

(Oh and the mesmers are still not liked)
I had a quick log in and noticed lots more bag slots in my storage (and 1 new one on my characters)
thanks
