So...based on some troubles we had with Modern War and Crime city on some previous events, we took the time to overhaul our guild matcher for this event in Kingdom Age.
Did anyone notice a speed increase at the start of the event? We used to sometimes take ~30 minutes to process all the matches right at the start of a war (everyone opts in at once)...this time it took 5 seconds.
Please note this does NOT guarantee instant matching for everyone all the time - particularly in the case of more powerful guilds sometimes we have to wait a bit to find matches of appropriate power level.
