how to make even bigger units?

[russia almighty]

The concept of a 243 late pahlavan kataphraktoi unit scares me.

[ludwag]

so how to increase, but not [screwing] up the balance of the game?

[Foot]

Well thats for you to test and decide. We made our decisions based on our own testing with game balance.

I was actually basing my statement on the experience of one who asked about it. I told him to try and he said it made his game crash, so if it's harmless he must have done something wrong and I apologize.

[konny]

Yes, it's harmless: you can raise the size of a unit in an ongoing campaign and also lower it, even though you have units of that type with more men than allowed in the game.
