Yeah... in other words, it turns out that the best tactic for the Stronghold is to develop a captured castle of another faction. :)
I just don't understand what the point is in playing as the Stronghold against strong players or at least those who are at your level. In my opinion, you might not be lucky here – a neutral castle might not have a Fort, or there might not be one at all; there might be too few resources, etc.
What then? Should you humbly wait for the enemy army to arrive and die with a sword in your hand? :)

Where did you get this nonsense from? Did I write this in my previous post? Please, read carefully what I write; it's already very difficult for me to type (because I do it very slowly and it's very hard for me; yesterday I spent the WHOLE night on posts here – and this is the result...).
I wrote about the possibility of building up either finances or troops in another captured city, or building up your own city in parallel (if you managed to find a lot of money in the first week), or, in some cases and under certain conditions (I already listed them above) (and they are practically the same for any faction, it doesn't matter if you are playing as the Stronghold or some other castle) – to abandon the construction of your native castle and move to a newly captured one. But nowhere did I write that "the best tactic for the Stronghold is to develop a captured castle of another faction. :)". Both I and Forrest wrote above how to play the Stronghold correctly (I don't want to repeat it again – please, don't be lazy and read it on the previous page)
