Agreed, but diversion is currently not worth the cost over sprint. The buff I suggested might be too strong tho, now that I think of it.
It does not have to "diversion" just a timed ability that increase the performance of the unit accordingly to what it needs (probably defensibly in this case maybe armor?) so that they player has to judge when to use the unit and ability for better results.
IMO, Ostheer doesn't need a generalist option for both AI and AT. The option to skip to T4 with the Panzer 4 H already opens the door for an easier Panther afterwards.
I tend to disagree. The original Ostheer design had them with inferior mainline infatry and superior support weapons and Tanks. They had to defend until their armor rolled out so that they could push. Currently going for PzIV's does not cut it since allies have armor that is equal or better that it. PzIV can even lose to AI specialized vehicles like the KV-8.
A decent medium that can fight armor above the standard allied mediums actually creates a new play style for Ostheer who would no longer have to relay on expensive expensive specialized units.
