I'll quickly expand on the Embassador concept:
Babayonce and I had a one hour meeting about it once in which we discussed the potentiality of at least Elven and Qadir embassadors. The idea there was to create an application based system where players could apply to become embassadors which grants partial instant nobility, but there was a catch. The player was required to do monthly/multi weekly tasks which were often detrimental to their relations with the other nobility and regalia. For ex. the Empire of Songaskia asks Embassador X to dig up some dirt on noble Y or have a law passed that makes Z no longer possible (for example racial religious discrimination of Songaskia by the confessions of Melennar).
Eventually this idea was just stuffed into a high hat and shelved. We didn't have the manpower to keep generating these tasks, especially since I'm so thin spread right now that I'm even having trouble maintaining the Guild Wars game, the current update almost being 2 weeks overdue. I don't think we currently have any new aspirants that would vaguely be competent enough to fulfill this role. Not that they aren't competent, rather, we "hired" them for different tasks which they are very competent in. The noble programme has always been a super niche of both Babayonce and myself and with extension Shuikenai. I'd be at a loss who else to assign to this sort of content generation besides myself, which quickly becomes a "Kill the Guild Wars game, or don't implement the Embassy system". It's a tough coin toss.
Granted another reason why this never occurred is because we didn't see anyone in the community who played the non-Ailor races who seemed to have the same level of effort, dedication and activity of say, the likes of Doc_Cantankerous, catcat1305, BillyTheScroofy, some of whom would later fold into staff membership partially also because they had so much input.
I don't know myself if this argues for too-high expectations, or whether it means that the rest is simply too unwilling to put a fair amount of effort in. You make the judgement call.
