I've checked the forums on sda and it seems the people there think guild wars cannot be run because it is a "mmo", multiplayer, time cannot be verified w/o a whole new account, I don't think that's the case as:
-the pve elements have set goals and final missions.
-it easy to verify and disprove cheating w/ the /age command at the beginning and the end of each video segment.
-multiplayer issue can be dealt with by the exclusive use of hero/henchmen
I think that it would be a fun project for the community to tackle the optimization routes and paths that the speed run would need and come up with strategies that are integral in these speed runs. Now I know some people are going to reply with tldr; and "waste of time" /12chars, but before you do, watch one of the videos of a game you've played either at sda or on youtube and see if it will change your mind. The runs are stunning, the game is deconstructed with amazing dedication. Some runners spend 8 hours recording and reloading to cut down a minute in game time by performing, dare i say, miracles, in the game. I think these speed runs are the ultimate tribute to a game and would be a cool challenge to undertake as well something exciting to watch. Not only that but I think we could all participate in this project with suggestions, tactics and input even if we don't plan on doing this run ourselves. Well that's all I have to say, just thought this would be a fun activity for the community.
