Heh, we had that once in a test map. I certainly hope we reintroduce it as it was epic.

Regarding the mortar, as everyone in the know has already said. Use the Mortar Freerunner correctly and it is the most effective supressive and destructive fire weapon on the map. The problem is people tend to charge in with it like it is a front line tank, which is exactly the right way to get you killed quick, but however is not the correct way to use the Mortar Freerunner, and another problem is that it is also best used while employing teamwork (unfortunately the idea of serious teamwork is lost on some players), hence the need for a foward spotter (like you would need using real world artilery) to paint targets for you to engage. If people hold the Freerunner back and use the targetting system you just watch the kills mount up.

Another way to use the Mortar Freerunner is to employ supressive fire on a CP that your team is attacking. Your shells have distance markers as you fire them so you can see how far away they are hitting. Use the distance marker on an enemy held CP to judge how far away it is and rain death on them from a distance softening them up for your team to engage. The Mortar Freerunner is one of the most useful assets on the map, you just need to know how to use it correctly.

Here endeth the lesson.
