[Lord of the Rings] I know it can only be speculation,but what were the Blue wizards doing in the east that was so much more important to them than defeating Sauron?

Prof Tolkien's research at first lead hin to believe they failed in the mission they were given, and started cults and the like. Later he amended his postion. He concluded they must have had some success in thwarting Sauron's attempts to dominating the East (by inciting rebellion/resistance).  His reasoning was that if Sauron did indeed have full control of the East (and all its resources) there is no way he would not have utterly dominated the West.

(This is not speculation by the way. It is fact about the Proffesor's research.)
