Missing notice about lineup changes for simulator battles

Why aren’t we announcing what’s being removed and added to the simulator battle lineup? Should users find it on their own?
In the past, the M48G2 and IS-7 were in the same lineup match, but were deleted, and Gaijin did not announce this. Recently, the Merkava mk2d tank was removed from the T-64A top-tier lineup battle. Why are you not notifying that this has been removed?
