What mistake did they make?
I think the mistakes they put in battlefield bad company was:
Only one helicopter in the game, They have appeared to of countered this by adding two aircrafts instead of one, and actaully aircraft on both sides. I think two aircrafts is a good idea because there is more of a chance to recieve aircrafts so there is no reason to team kill someone who gets an aircraft before you.
Adding more than one anti aircraft weapon per bases and generally more on the maps, to balance it out.
Taking away team killing as people like yourself exploit it.
TKing in BFBC had any effect on TKing or the number of vehicles in BF1943
Well can you explain why they removed team killing, and please consider removing team killing would not of cost them a single penny, and I am aware it is a low budget game.
