I am not sure what your OP was prior to editing, but I assumed it was something along the lines of how great it is to have 100 unit armies, or just 40 unit armies in the case of this thread.
Honestly I don't even play Rome 2 anymore because the more I touch the game the more I hate it. I am putting it away for now in hopes that mods can restore it to bring back old enjoyable memories of past TW titles.
So this actually has prohibited me from testing and even bothering to work on this guide to make the game support more than 35 units/army. Unfortunately I can't change the title of the thread.
