For the record, that five-hour period didn't happen for us at all, so we were never allowed to reinforce for any of our three sieges or one raid, and we were not able to reinforce even the first minute after the next siege was declared. We were just lucky that it took KUTT six years to get enough equipment to raid us so we could learn that recruiting troops in a village is ungodly slow and that you get to choose between earning gold and recruiting troops. We did get some good gear off of our first and second attackers, but other than that, we could only afford to buy "Practice <weapon>".
Something that would be helpful for new clans: any documentation. At all. Anything. The outdated forum posts that rarely get updated and aren't from anyone who actually knows don't count. It would also be nice if we either had a cooldown period between attacks, or a way to transfer troops/equipment/gold to and from our village for a short time after being attacked. As it is right now, we can be (and have been) DDoS'd, although by different people and, I assume, unintentionally, except for the raid-siege combo.
Just out of curiosity, why do raiders get to keep all our stuff? Stealing gold and killing troops and even population would make sense, but I don't understand the value of this part of the mechanic.
