With this event, I can see the new strategy for little clans to turn their tide against big clans or vice versa.
Everyone in clan get like 10+ accounts and stay log on so server is population hits maximum, and since castle/fort owners can't log on, it's an easy takeover.
Worst, adena sellers can use this to takeover all the castles and make more money.
Now, making no limit to account creation is not a problem?
