Not to be bad or anything, but, I don't see much admining on con sites when deployed. Some random dude can place one and it's hard to punish them. At least, if people are building something, you can see who's doing it.
Still, the c-sites are hard to enforce unless you can catch em red handed. Still would be cool if we could like build catapults as attacks or siege towers and stuff. Would make siege way more interesting. Plus, it'd help in preparing for strat sieges.
Also considering the devs, i doubt it'll get fixed anytime soon.
