The almighty commander
This function is what´s really going to define this game during clan wars. The commander is not a player on the field, he is more of an entity controlling and supervising what happens on the battlefield. He has a top down view of the map and he can call in artillery, drop ammo crates and set waypoint for his players. In fact, the commanders view looks like a completely different game, more like an RTS thingy, Command&Conquer style really. As long as your teams radar stations are intact he can see _everything_ on the map. And where he can see he can shoot artillery - although the artillery is being balanced with a long reload time, so, the commander will have to choose his targets wisely . The only way to stop him therefore is to take out the radar stations and the artillery. It´s easy to imagine the first few minutes of a clan war is going to be all about commander vs commander, them trying to kill off each others radars and artillery. If your teams commander can't see or shoot he´s pretty useless. But radars and the artillery can always be repaired, Im guessing that the commanders best friend is going to be some poor bastard playing as engineer standing by to repair his toys

Since the commander can see it all, there´s no use for old tricks like contesting on roofs etc. It will be very interesting to see how the clan community decides to use the commander.
