The new Shieldwall-AIshieldwall formation is reformable in combat like in some other popular mods. I did this because I saw that this formation performs well with cinematic mods and is easily lost just by right clicking too many times. The downside is that it is unrealistic that a unit would form this in the thick of combat AND retain their charge bonus. I made a compromise by creating a shieldwall that takes 12 seconds to form during which the troops don't put out much damage. This shieldwall is a bit weaker with defense vs the advanced shieldwall used by elite sword units that are using "phalanx" ai. However, since it one can repeatedly charge then re-form the normal shieldwall, the difference is justified.
