Websites are often an important part of getting someone started in the game. There have been great improvements over the last several years with GuildWars.com
This new and improved website offers a slick and pretty layout, however a problem plagues the website that may ruin it for some...how unorganized it is!
An example of the unorganizedness (is that a word?) are:
-> Clicking on any link in the flash menu will take you to a new page. On this new page it shows the links contained in the page and also the very same links on the side menu. Seems kind of redundant to me?
Perhaps a little not professional?
Now here are my suggestions:
1) Add detailed information for the Assassin and Ritualist
2) Add seperate sections for Guild Wars products: Prophecies and Factions and detailed features of both.
3) Add short clips of each profession in action! Is there a better way to show them off?
4) Add and update skill descriptions for all of the professions
5) Add an "In Development" page to tease the community with future improvements.
6) Update the ladder page to match the new layout
*Add detailed information on all of the guilds history (Who they played; Win/Loss; win ratio, etc...)
7) Add "Screenshot of the Day/Week" for community submitted screenshots. The UI must be turned off!
8) Website schedule page with information on what website content comes out each day (I.E. Wallpaper wednesday -> Wednesday)
9) Fansite spotlight: Choose a fansite and recognize them each week/month
10) Video recordings of matches taken in observer mode (Not just during the tournament)
11) Website poll! I know this is coming I just had to put it in here

12) Add Cantha to "The World"
If you can think of anything else, or want to expand upon what I have said post something!
