You keep saying that, but I don't think it's true. I'm pretty sure the attack shouldn't have been possible in the first place.
There are beta testers but nothing is really tested if you are right, strange.
Maybe chadz should stop strategus and fix the bugs and exploits and then start with a wipe.
I suggest making a think tank about exploits and bugs.
There are not only cities a problem. AI doesnt buy throwing weapons, no good shields and 1hs, always war cleaver, arbalest, long bow and so on. There is no variation in equipment. Spawn camping at flags, flags always on walls, catapults make walls useless and many other things like op arbalests...
Lack of clear rules, if you cant code something at the moment, you can make rules to stop people exploit, like lock a castle for a week with fake attacks.
