I'd have to say the most annoying thing in KoC is none of the above. What annoys me most is when you have almost saved up enough for another Dragonskin just to have someone steal 90k from you. Now that's annoying.
I don't think Age 2 will last only 3 months. If that were the case the makers would be working on it as we speak. Getting a site like this to work perfectly with no bugs take a lot of time and they can't really start on new age if this one isn't working properly. They are going to keep fixing bugs and stuff until it runs as smooth as possible, then start work on the next age.
In Age 1 the most money I stole in a single attack was like 80,000 I think. In Age 2 though the most I've gotten has been like 14,000. I'm still weak! :hmmm:
