Millenium just for Martyrs?

Revelation 20.4-6
Then I saw thrones, and they sat on them, and judgment was given to them. And I {saw} the souls of those who had been beheaded because of their testimony of Jesus and because of the word of God, and those who had not worshiped the beast or his image, and had not received the mark on their forehead and on their hand; and they came to life and reigned with Christ for a thousand years. The rest of the dead did not come to life until the thousand years were completed. This is the first resurrection. Blessed and holy is the one who has a part in the first resurrection; over these the second death has no power, but they will be priests of God and of Christ and will reign with Him for a thousand years.

It seems from a literal reading of this text that the distinct reward of those who are beheaded for the faith is to reign for a thousand years. I am ok with this either way because death is like time travel anyhow and my next waking moment will be the post-millenial kingdom. However, the idea of ruling the nations under the Messiah is a major part of my current hope. Does anyone have a solution to this?
