The Orthodox don't ignore Revelation; they just don't wish to make doctrine off of something that is so jumboed up. If what I'm being told is correct, they pull it out once a year, read it, say, "Hmmm...how interesting.", and put it back on the shelf until next year. Personally, I can't say that I blame them. If people for one moment took God's command seriously that teachers will be judged more strictly, I think most of us would bite our tongues on things we really don't understand.
While there is also much we do not understand, there is much we do.
Revelation, combined with Old Testament prophecies (it is really a completion of the Old Testament promises) is not as difficult as many make it out to be.
As Mark Twain once quipped, 'it is not the things in the Bible that I don't understand that bother me, but the things that I do'
