As a ruler, the couple ambassadors that I've appointed have all just eventually gotten bored with the class.
Sure, there are treaties to write and negotiate every now and then, but it just isn't something you get to go and do every day of the week. Especially like now in Atamara where it's one alliance vs. another alliance and not much is changing every day because wars take time.
The ambassadors got bored and felt they were wasting their subclass, I suppose.
Alot of the fun of being an ambassador is the RP value. If you can't make use of that, then yes it is a pretty boring class. Every now and then you write a treaty, other then that you have slightly better diplo actions.
