I'd imagine then the sieges would be huge.....
Like honestly, after the first wall all your siege towers and catapults and ladders would be used, so you'd need to keep pressing..
But thats what im hoping?
You know, take the first wall then the enemie can sit there for abit and wait 10-15 minutes before bringing and reinforcements.
I like the fact that i dont have to feel rushed into taking over a castle. Like really if you've taken the first wall most likely you'll want to regather your troops and such.
Then again depends how the "Recruiting Units" thing works.. because then you can expect a counter-attack.
