If this comes across as rude it's not intended... but
Instead of asking us, how about you do your OWN research into what's changed in GW2 since release.
Here's a tip.. http://wiki.guildwars2.com/wiki/Game_updates is the webpage you need.

Well maybe it was the /sigh was what made you come across quite rude.
A list of everything they've added doesn't help me with seeing what the general reception of the game is at the moment.
That doesn't mean much to you though does it? Anything to reply like an ******* instead of ignoring my post if you think it's worthless.
