Though I'd mention that the dynamic spawn timer is now *LIVE* in siege thanks to Paul.
This means that on NA2 and EU2 when defense population drops below certain thresholds, the game reduces the respawn timer to compensate. You will see that in this situation you will spawn and still have some seconds counting down on the timer.
The goal is that this will remove the dreaded "lol pop, offense wins" issue.
This, of course, has been more of an issue on NA2 than EU2, but it's good nonetheless.
Rejoice, and praise Paul.
