Well, we knew it had to happen sometime soon, MMO-champion reported that you can now pre-order Warlords. It comes with a boost of a toon to 90, effective immediately. (You can also boost a toon for $60 if you want to do that. There is more info on that below their current post.)

And thanks Tonkah for the heads up on this!
