Yep, I wasnt sure what huge units was, I thought it had something to do with the scale that the units are rendered. Reason I ask is that I'm having alot of trouble with the hordes as WRE, not so much defending my lands from them but not being able to destroy the horde after Ive taken their last settlement.
Now the slavs have invaded and its kinda disheartening as there are huns, lombardis, slavs and goth hordes roaming everywhere and I seem to spend most of my money per turn keeping revolts down and recruiting peasants to keep up with the population growth. I'm playing on M/M and cant make enough money to create enough armies in order to expand past the hordes. I've been following a few of the strategies listed here, including trying to convert everyone to christianity(which led to nothing but a volatile mix of religions in pagan cities) and disbading units/demolishing military buildings. Also somebody wrote that if you leave a settlement to revolt and have destroyed all the military buildings the western rebels that appear will only be equipped with peasants, this is true but a general will also spawn in that settlement and they will have heavy cavalry bodyguards. How are you supposed to take these towns back so quickly if you've disbanded half your army??
I will keep trying to build econ buildings and defend more, until i can get a decent amount of cash to raise a proper army, bridge defense works well but if your really outnumbered with cavalry they can just smash through your defensive line and trying to bottleneck them at the bridge wont work since you will get routes. Right now I have all the original settlements plus a few more that ive managed to capture but still dont have a clear idea on how to deal with hordes, especially after you capture their final settlement and they spawn 4 large armies.
