1. I play commander because I want those 10h command time for this stupid ribbon. OK J/K I try to motivate my squad leaders by supplying them with crates, UAVs, vehicles and by sending "commend messages". I try to use arty as requested support because I hate blowing up succesfull squads but I prefer to use the arty as close to my squads as possible instead of using it for baserape.
2. Why dont u play commander?
I think the commander is a score whore right now and I hope that they will change this in BF2142. I think the BF2 commanders biggest disadvantage is that he can't paint his ideas on the map. Why can't I show every soldier what role they play in the big picture. Right now a soldier does not have a single clue where he fits in and if this order is coming from his squad leader or his commander.
