Was anyone complaining about this? I don't see why it had to be nerfed into the ground, I've only ever seen it used once anyway, and the attack failed horribly.
Of course people are complaining about it, it makes your entire army skillblob into one pixel on top of the captain, INCLUDING TEAM WEAPONS so that your opponent can conveniently destroy your entire army with one well placed indirect fire weapon of his choice.
So this way instead of creating a hilarious micro nightmare for yourself by clicking this button you just get a nice accuracy buff and your team weapons will hold still and do their job. The munitions cost isn't that much and suppression immunity (Fire Up! Heroic charge!) has always been stupid so it makes sense to remove it.
