When using team chat to speak team wide, implement automatic labeling for player location. Ex: Znombie [EBG]: Enemy zerg on keep.
Too many people aren’t stating their map location (Ex: EBG, YBBL, BGBL, ect.) before making calls. Most people aren’t even aware of the change, and its only going to continue since new players will not know, and returning players will be clueless.
