Касательно таймера:
To find out when the next battle is starting you can go to the Portal Mage in Dalaran, visit the Zone itself, or view the World Map, which (as of patch 3.1) now displays a countdown timer for the next battle when viewing the Wintergrasp zone. As of patch 3.3.3, this timer is always accessible, whether your character is in one of the Northrend zones or not. Formerly, it would not display if you hadn't been to Northrend since logging in and would display the last known time if you traveled to an area outside of Northrend.
Касательно создания машин:
In order to create vehicles in Wintergrasp, you must attain a rank of Corporal or better during a Wintergrasp match by killing enemy players or NPC guards. Once a vehicle has been created, any player can pilot or operate a turret on one. Vehicles are created at Goblin Workshops under your faction's control. These factories can be captured by the opposing team.
As of patch 3.2, factories can no longer be destroyed.
