Re-reading Franks post reminded me of one of the reasons that I have a problem with EA other than its impact on the game.
The original designers took great pains with the math of the CRT to ensure that there was no difference in expected results when 2x3SPs fired at a target or a single 6SP unit of the same type did the same. There is only a minor difference if units "volley" fire or not (see thread on Volley Fire).
They came up with the Indirect Fire target density adjustment to try and do the same for artillery.
The trouble with EA is that it does matter. Once you have reached the threshold of "victory" on the new assault CRT then you are better off assaulting separately as many times as possible rather than all at once. This is due to the "bottleneck" final morale test.
This breaks the essential modeling of "simultaneous" action in a turn.
If an alternative is conceived of in the future I hope that its designers will bear this issue in mind.
