It's horribly ahistorical and is generally considered a blight, pointless, and dumb. My personal opinion is that it is kind of dumb, but it adds something to Western Europe that wasn't there before(and still isn't in India) and that is some big event or disaster that really shakes things up. However, Your Mileage May Vary.
