I don't agree that a Monarchy will have a bigger army. In fact a Republic might have a bigger army due to more cash-rushing/upgrading. A Republic will only have more unit support. War Weariness doesn't become too much of a problem once you know how to manage it well. A pike behind city walls doesn't spell death to cavalry all too much (I don't know the exact calculation, but cavs. vs. pikes makes a VERY good match up if you have the cavs and they have the pikes), or more advanced units, or knight armies, especially once you have the military buildings which make armies stronger. You can find a bunch of pics which help to analyze the potential of a Republic on a Huge map here.
