Since I was the GM who started this I shall give my point of view
Firstly when I started to receive complaints from players and I looked at the Plaza there were 6 or 8 players taking it in turns to duel by the fountain, hardly a war situation and it wasn't till I started to follow them to the arena I saw more
Secondly I asked repeatedly for the fighting to be moved to the arena where it belonged and the players finally agreed saying they were informing their guilds
Thirdly after my fourth warning shout I started Freezing and raising out of combat reach and finally it was taken to the arena when I had finished and some sort of order was established I thawed the players intending to bring them down unharmed but they must have moved because they all fell before I could lower them, I did
not drop them on purpose after all I could have just teleported them to the DR with the same effect.
In reply to those comments that the guard doesn't exist or crossbows don't exist because they aren't implemented yet neither are opening doors but does the entire population of Hydlaa (est 1000+) sleep in the streets?
As for crossbows maybe a mage could get a spell off in time to defeat the firepower of a crossbows 2-4 shots a minute, but I'd be surprised if a mage could stay concentrated under the 10-15 a minute a good longbowman can get off
At no time was there 60+ chars fighting at once on the plaza 20 tops and mostly right under the guard tower so the guards would have the advantage of higher ground as well as a fortified defensible position
Whether the war was IC/OOC or just for fun didn't really bother me at the time and the only thing OOC about fighting in the Plaza or any of the public areas is assuming there will be no reaction from guards or that there are no guards, purely because we haven't had time to implement a proper Hydlaa Guard detail
