BF really bungled the assault rules with this new update. Many players are just saying 'no' to the new rule and ignoring it.
All this to favor big armor. Now even if beaten badly in an assault and forced to break off, you can push the victor out of the way with impunity. No need to think. Clearly no one at BF was thinking. This is proof positive that the BF team needs to talk rules over with a select group of experienced players before publishing. They clearly are not playing the game, and are clearly not communicating with the thousands of players.
