The thing we really need is to separate the Armored divisions. Okay, I confess, I've played too much WoT.
We would have Light Armour (well we already have this), it only upgrades to Light Armour.
We would have Medium Armour (we already have this), it only upgrades to Medium Armour.
We would have Heavy Armour, it only upgrades to Heavy Armour. As few numbers as decisive in battles.
And of course the Superheavy Armour stays a brigade as it is now. Although it would be funny to see whole Maus divisions rolling forward.
And after that we would have the MBT. You could only research this after you have reached the top medium and heavy armours. Both of them would upgrade to MBT.
