While it is true, that elves are endangered, and they do not have a lot of time, thanks to their life spans, we are talking about decades, if not centuries, assuming that once they have enough half-elves, they do not start killing off the elves.
That said, even if the elves can hold out that long, this is a game, so we don't have decades to make this a reality, or to wait for the pendulum to swing back and forth a few times before it stabilizes. So it will likely need to be a drastic plan, but one that lasts, without putting too many people at risk.
