Are you aware that ESN sonar no longer works? There is no current fix for this and there is no responce from moderators on the battlelog forums.
Before the latest patch, it was wroking. Please explain why there has been no communication from EA regarding this issue? I have contacted ESN directly via email and they fail to respond also. As a customer of EA from 2000 - 2012 across various platforms I feel like I am being cheated of a service and with no explanation.
