On one hand hats off to CCP. Some 4,000 players apparently trying to fight and the node did not die.
Against that, the node not dying resulted in a situation that was unplayable for many of the participants. That is no fun at all.
So where does CCP go from here? Do they look at Drones to reduce some of the server work? Do they look at a mechanism that freezes the system when x number of players are on grid, splits the grid and moves half the players on to a new node, then restarts? Do they simply restrict the number of people who can be on any one Grid in game? Do they limit how many people can use one Cyno? Do they change the Sov mechanisms so that these sorts of battles will no longer influence it? And how do they do all this without making it easier for smart players to game the situation, or have it seem so contrived that the game loses its immersion factor.
No idea what the answer is, but I know the players are pushing CCP into a situation where they are going to have to try something new to help the situation.
