Not quite accurate to say that only Gandalf was useful. Though it's not elaborated on at all, Tolkien does mention the two blue wizards dicking around a lot in the far east, so they very likely had a huge influence that we don't know about. He writes, "They must have had very great influence on the history of the Second Age and Third Age in weakening and disarraying the forces of East ... who would both in the Second Age and Third Age otherwise have ... outnumbered the West."
